Abstract

A vehicle safety belt link point assembly for attachment to a pillar of the vehicle at a location adjacent the shoulder of a vehicle occupant, includes a slotted guide with one link provided with a series of locking openings. The guide is secured to the pillar. A slide member is mounted on the guide and has one limb lying adjacent and parallel to the limb of the guide. The slide member limb has one opening which can be made coincident with any of the openings of the guide member limb. A slide piece carries a link point for receiving the belt webbing and is movable in the slot of the guide. A link is movable with the slide piece and carries a projection which can engage in a selected opening of the guide limb and with the opening of the slide member to lock the device.

Claims

1. A device for the adjustment of a link point of a safety belt arranged adjacent the shoulder of a vehicle occupant comprising,

a slide member having

an angled leg with a locking opening therein,

an adjustably lockable link point carried by the slide member,

a guide mounted within the interior of the vehicle, receiving the link point and having

a limb with a series of openings therein,

a slide piece movable in the guide and having a tapped bore therein,

a bolt screwed in the tapped bore which connects together the slide member and the slide piece,

a locking device to effect the adjustment and locking of the slide member,

a return spring biasing the locking device to the locked configuration,

said locking device being movable substantially perpendicularly to the direction of the movement of the slide member and being connected with the latter, and engaging, in the locked configuration of the slide member in one lock opening of said series of openings, and

a link movable in the slide member and carrying the locking device which latter in the locked configuration also engages in the said lock opening in the angled leg of the slide member,

said angled leg of the slide member engaging over the limb of the guide and lying substantially parallel to the latter and

for the guidance of the locking device a respective guide surface is provided on the slide piece and a guide surface is provided on the link.

2. A device according to claim 1, wherein the slide member carries,

two pegs,

the link has two elongate holes, and

the slide piece has two bores, one on each side of the tapped bore,

said pegs engaging in a respective one of the said two bores and traversing the elongate holes so that the link can make guided relative sliding movement with respect to the slide member and the guide.

3. A device according to claim 1, wherein said link includes,

projections,

the slide member has corresponding slots through each of which a respective said projection passes, and the device further includes,

a two section return spring, each section abutting one of the said projections.

4. A device according to claim 3, wherein the slide member comprises a pin disposed between the slots, an intermediate section of the return spring being wound around said pin.

5. A device according to claim 1, comprising antifriction inserts disposed respectively between the link and the slide member and between the slide piece and the link.

6. A device according to claim 1, wherein in the locked configuration of the slide member the locking opening in the angled leg of the slide member is aligned with one of the locking openings of the limb of the guide.
