Anchorage means for vehicle safety belts.

摘要

An adjustable shoulder anchorage assembly for a vehicle safety belt, comprises a vertically extending track (10) mounted on the interior of a vehicle body above the level of the shoulders of an occupant of an adjacent seat, and a traveller (22) mounted on the track (10). A guide member (24) is secured to the traveller (22) and has a slot for receiving the strap of a safety belt. A latch member (28) is movable transversely of the track (10) between an engaged position in which a latching formation thereon is in engagement with one of a series of complementary formations (12) on the track (10) so as to inhibit movement of the traveller (22) along the track (10) and a release position in which the latching formation is disengaged from the track (10). A cam follower (34), on manual release means (38), is operative to engage in a slot (36) on the latch member (28) so as to move the latch member (28) between its engaged and its release positions in response to movement of the manual release means (38), and resilient means (42) are operative to bias the first cam formation (34) into a position in which the latch member (28) is in its engaged position. The part of slot (36) in which the cam follower (34) engages when the latch member (28) is in its engaged position is oriented perpendicular to the direction of movement of the latch member (28) between its engaged position and its release position. Thus, application of a force to the latch member (28) in a direction tending to move it towards its release position does not cause the movement of the cam follower (34) necessary to permit such movement of the latch member (28).
