Abstract
An anti-creep bar for holding a web. A seat belt buckle or tongue has a pivotally cam bar which receives a seat belt or web. The cam bar is positioned adjacent a web stop and pinches the web therebetween when in the locked position. A pair of wire springs urge the cam bar to the locked position, but are yieldable to allow the cam bar to pivot away from the web stop when the free end of the web is pulled outwardly.
Claims20
A seat belt device comprising:
- a web having a fixedly mountable proximal end and a free distal end;
- a frame including mounting means and a web stop;
- a bar movably mounted by said mounting means to said frame and having a locked position for holding said web tight to said frame and an unlocked position to allow said web to move around said bar and relative to said frame, said bar in said locked position applying pinching force to lock said web between said bar and said web stop;
- and,
- spring means located on said bar laterally outward of said web extending between and received by said frame and said bar, said spring means operable to normally urge said bar to said locked position but yieldable to allow said bar to controllably move to said unlocked position, said spring means further operable to maintain said bar in said locked position even though said web momentarily loosens on said bar as web force from said proximal end to said bar is varied and until web force from said distal end to said bar moves said web and moves said bar away from said web stop.

The seat belt device of claim 2 wherein:
- said spring means includes a pair of separate springs mounted to said frame and to said bar.
A seat belt device comprising:
- a roller bar with opposite ends;
- a frame with a pair of apertures, said roller bar with said opposite ends being movably mounted in said apertures, said frame also having a slot with a web stop extending adjacent said slot and parallel to said bar;
- a web extending at least partially around said bar;
- spring means located on said bar laterally outward of said web, mounted on said frame and received by said bar, said spring means operable to limit motion of said bar and to position and releasably hold said web against said web stop limiting relative motion between said bar and said web, said spring means further operable to maintain said bar in a locked position even though said web momentarily loosens on said bar as web force from said proximal end to said bar is varied and until web force from said said distal end to said bar moves said web and said bar away from said web stop;
- operable to retain said spring means on said frame;
- and,
- second holding means on said bar and receiving said spring means and being operable to retain said spring means on said bar.
