Question Seat belt bolt for crotch

Hi all,

A couple of Q's please for all you engineering guys out there :-

I am fitting the Vans crotch strap kit for my Hookers and an AN5 bolt is supplied ( which I am aware is too short for the Hookers ) so I sent the following Q to Vans

Question "Why does the 5th point seatbelt require a AN5 bolt when the
others use a AN4 and can there be any slack between the bushings and the
seat belt attachment tang eyes...I am assuming that any slack would be
undesirable in the event of a sudden deceleration where the bolt may then fail

Answer :- Don't know why"

Sooooo my Q's to the Forums are :-

Q1
Is movement (other than rotational ) between the belt attachment and anchor point undesirable ?

Q2
Why a different bolt type between lap/shoulder strap attachments and crotch strap attachment ?

Thanks

Hi CJ,

Thanks but that still doesn't answer my specfic Q's.....

any engineers out there who could provide some input please

By the way re Q2 by definition would a AN4 bolt be sufficent for the crotch strap

I think rephrasing your questions for more clarity would help people in answering them.

Q1. I would say that YES, any movement would be a bad thing as it could (and likely would) lead to wear. It is my estimation that the bushing should be tightly pinched between the brackets.

Q2. Not sure, but I dare say the AN-4's are likely to be sufficient.
