Britax Multitech

Merci pour ta réponse

Et si l'enfant ne fait pas 9kgs mais a déjà 16mois ?
Bon en gros j'ai encore un peu de marge dans la coque mais ça va durer jusqu'en janvier février je pense mais elle ne fait aps 9kgs actuellement. Et vu qu'elle prend même pas 100g par mois ....
ça fait un peu comme n°1 quoi, un modèle crevette...

Je confirme, j'ai vu le siège de Xavi, il est trop raide pour un bébé d'1 an, pas assez contenant. par contre dès 2ans, l'enfant se tient mieux. Il est par contre super: l'assise est bien droite, la tête est bien tenue, il prend peu de place finallement ( à l'avant de la 206). Côté confort, c'est 1britax, 1peu dur à mon goût mais somme bcp de sièges!!
Ninette, Xavi m'a dit qu'il était un peu long à remettre en place lorsqu'on le changeait de véhicule.

Moi je pense que ça passe avant 2 ans. Si beaucoup de sièges sont assez durs c'est pour de raisons de sécurité aussi, ce n'est un canapé.

Voici un enfant d'un an, 9 kg et 79 cm dans le MT:

je trouve que le cale tête est bien trop haut on voit même le harnais qui remonte énormément ! il ne peut pas se baisser plus ? parce qu'il a l'air top confort le multitech!

Le fait que le harnais ne soit pas juste à la bonne hauteur n'est si important dans les sièges RF, parce qu'en cas de choc l'enfant est plaque contré le siège et c'est le dossier de celui-ci qui va absorber en grande partie les forces d'impact, tandis que face à la route seul le harnais retient l'enfant.

mais si le harnais est trop haut, bébé peut en sortir plus facilement, non ?
c'est ce que j'ai remarqué !



(je me replonge peu à peu dans mon dossier, et je récolte le plus d'infos possible, précises, sûres...)
je t'envoie un Mp à ce sujet d'ailleurs j'ai consacré un chapitre à
bien ajuster les ceintures/harnais à la taille et à la corpulence de votre enfant

Non, parce qu'il sera projeté vers l'avant avec infiniment moins de force qu'un enfant face à la route. Le fait d'être dos à la route change tout.

The harness height is fine. It is slightly above the shoulders, which is fine

Lena

Lena, do you confirm that a one year old is safe and confortable in the MT? Some people here seem to doubt it.

Merci pour les photos Kumonosu. ça me confirme dans le fait d'attendre un peu car le mienne est quand même bien plus petite donc je pense que même au minimum le harnais sera trop haut mais comme je peux le tester en vrai que je pouvoir me rendre compte par moi même. Sinon coté confort pas de souci pour moi après l'avoir vu je le trouve bien.

The guidelines for the Multi-Tech are:

- Being able to sit unaided for more than 20 min. Some children come to that point at around 9-11 months of age. some childrn reach that milestone before 9 months.
- recline angle of the MT is also something that should be counted for. It can be steep in some cars.
- The harness should be at or slightly above the shoulders. (not touching the ears)

The pictures of the seat in this thread show a large recline angle which has been forced by pulling the tether straps. Be VERY carefull with this much recline angle when the children grow older. The recline angle is too much for older children.

Lena

Oops. My son is four and half years old, but I never thought the recline angle was that big. We'll push back the passenger seat straighten the recline angle.

on which photo the recline angle is too much?

i thought, that the angle is nearly the same when the seat is installed correctly, no?

in the manual is written this:

"Pull the footprop away from the back of the child seat as far as possible" and "....at an angle of 100° to the horizontal"

so, when this is done, the seat can't be reclined to much?



and it doesn't matter, if the footprop is not put away as far as possible, like on the photos above?

I think she's talking about the photos at the beginning of the thread, which belong to our MT in our car ( Ford S max ).

It is not the footprop that creates the recline angle. It´s the people installing the seat. This is done by way of pulling the tethers hard, so the seat comes off the swinging base.

Locking the footprop is the last thing that you do, during the installation process.

The footprop should not be put as far back as the strap allows. It is 100 degrees from vertical line. That´s it. there is a ruler in the back of the user guide that you place horizontally under the crossing bar of the footprop. If you have to put the footprop as far back as th strap allows in order to obtain the 100 degree angle. Then that´s what you should do.

The issue with reclining the seat as much as in Herbiz´s photos and Kumonosu´s with older children is the fact that the children will ride UP in the seat instead of INTO it. This can result in head injuries as well as neck injuries through neck compression if th child´s head hits the front seat or front screen. Another issue is that in an accident - say a frontal collision, the seatbelt will stretch as the seat pull towards the front of the car or towards the back. This means the seatbelt can become too loose unless you put something between the seat and the swinging base, which is not recommended by the manufactorer , because this is not tested, so no-one knows how the seat will perform with a roled up towel or so. Adding household supplies such as a towel counts as modifying the seat. A seat should perform to a certain standard without add on products

Putting something between the seat and it´s swinging base is NOT unsafe per say. IF manufactorer allow add n products to be used with the seat, you can bassicaly choose to put a pile of papers inthere, which won´t be a good idea at all. people can easierly put something inthere that won´t be safe in an accident. i have asked britax about this, and this was their reply.

from what I can see in all the photos of rearfacing cars eats on this board, the front seat bight is used for tethering the seats.

IF there is a gap between the footwell and the front seat rails, it is perfectly safe to install the tethers in the front seat rails This does tend to ease the installation quite a bit i most cars. getting a firm installation without pulling the seats off their bases is somewhat easier this way.

ah, ok.... thanks for this information :)

i thought, that the seat have to be pull very hard.. if he is not, the the seat is not so stable...

but locking the footprop, is it really tha last thing?

"Pull the footprop away from the back of the child seat as far as possible 1
(dia 2i). Whilst maintaining the correct angle, lower the footprop until it touches
the fl oor 2 . Make sure that the footprop is securely locked in place by pulling
the sliding section of the footprop.
Finally ensure that the tether straps are fully tightened by pulling the loose
ends downwards (dia 2j). "

i also make like this, so pulling on the tether straps at last thing

It is not! You won´t see a professional fitter lock the footprop prior to tightening the tethers. Furthermore it is not what the user guide instructs you to do. It does say to tighten the tethers prior to releasing and locking the footprop. That last bit is something you do merely to retighten the tethers if you have to loosen them a weeny bit to make the footprop lock.

The fact that the seat is a bit unstable if you do not pull very hard, is merely the fact that you have installed the tethers in the front seat bight. This can cause problems in some cars. The problem is usually solved by installing the tethers in the rails instead.

yes, thats what i mean ;) Buckle up the tether straps (i use my weight to pull them tight) , than

adjust the angle of the footprop and re-release it, an than tighten the tetherstraps again a little bit.
when the footprop is locked, normaly it is not possible to thight the tether hard...

Je confirme que ma fille a 20 mois et elle utilise ce siège depuis 15 jrs (je crois). Et elle est très bien dedans, même si je pense qu'elle est plus "confort" dans son kiddy.
Sinon, effectivement, c'est un lpeu ong et pas trop pratique pour changer de siège. En fait, il faut pas le faire tous les jours. Une fois par semaine, c'est pas trop grave.

Voilà!

En tout cas, ça m'a vraiment fait plaisir de rendre service. Et j'invite les forumeuses (...eurs aussi) à montrer leurs sièges en vrai, c'est vraiment appréciable pour ce type d'achat.

bonsoir
je suis désolée mais j'ai essayé de traduire les réponses en anglais mais je n'y comprends rien ; sur quoi doit on être vigilant lors de l'installation ? L'inclinaison , les attaches ? Comment l'attacher au siège avant alors ? Je sens que je vais regretter l'installation de mon besafe .

It´s difficult to overrecline Besafe seats, since they don´t have a swinging base like the one the Multi-Tech has. Also Besafe seats are sold with 2 pairs of tether brackets, that you mount on the frontseat rails if there is no gap betwen the rails and the footwell.

I allways recommend installing the tethers in the front seat rails.

1. It´s easier to install the tethers
2. No need to readjust the tethers if you want to alter the position of the front seat.
3. Easier to get a tight installation of the seat
4 reduces the risk of overreclining some seats when usd with older children.

Install the Besafe with the seatbelt first. Then you move on to buckeling the tethers and tightening them (give them a good tug).
You may have to tighten the frontbrace some more after tightening the tethers.
Last, you adjust the footprop and lock it into place.

Lena

For front seat installation.

You just leave the tethers whre they are an route them underneath the front seat (cross them). Put the seat itself in the front seat and pull the front seat as far forward as possible. Do the seatbelt, buckle up the tethers and pull to tighten them good. Eventually adjust the front brace. Last thing is to lock the fotprop into place. Locking the footprop of the Besafe seats can be a bit of a squeeze.



It is highly likely that you can move the tethers up when installing on front seat, as shown here:




However, the risk of overreclining a seat when installing it on the front seat and mounting the tethers in the front seat bight is reduced greatly. You don´t tether the seat forwards.

Besafe on front seat:


On backseat



look at the difference in geomitry of the tethers. That´s what makes the difference.

The issue with a high recline angle when used with an older child is that when the child will ride UP in the seat more, increasing the risk of head to front seat contact. When installed upright the child will move INTO the seat rather than UP towards the front seat.
