Abstract

A member across which a seat belt passes carries a movable member which moves between first and second positions in which the seat belt is respectively gripped to inhibit rewinding. The member is attachable to a seat belt guide in a vehicle by means of a screwed rod which is pivotally connected to a guide engageable hook. The rod permits the member to follow twisting movement of the seat belt.

Claims

1. A control device for an inertia reel seat belt comprising a member across which a portion of the seat belt passes when in use, a movable element mounted on said member for movement between first and second positions in which the seat belt is respectively gripped to inhibit rewinding and released to permit rewinding, and attachment means pivotally connected to the member for engagement with a mounting on a vehicle and which allows the member to swivel about an axis extending in the longitudinal direction of said portion of the seat belt to enable the member to follow twisting movement of the seat belt, said attachment means comprising first and second portions interconnected by a pivot element defining a further axis of swivelling transverse to the first said axis and about which the member can swivel, said first portion being pivotally connected to the member to enable the member to swivel about the first said axis and the second portion being engageable with the mounting on the vehicle.

2. A control device according to claim 1 in which said attachment means is connected to said member by means which permits the position of the member relative to the mounting to be infinitely varied in the longitudinal direction of said portion of the seat belt.

3. A control device according to claim 2 in which the connection between said attachment means and said member enables said distance to be infinitely varied by rotating the member about the first said axis.

4. A control device according to claim 3 in which the first portion is screw-threaded whereby rotation of said member about the screw threaded portion causes the longitudinal position of the member relative to the mounting to be infinitely varied.

5. A control device according to claim 4 wherein the screw threaded portion is located in a channel formed in the member.

6. A control device for an inertia reel seat belt comprising an elongate member across which a portion of the seat belt passes when in use, a movable element mounted on said member for movement between first and second positions in which the seat belt is respectively gripped to inhibit rewinding and released to permit rewinding and attachment means pivotally connected to the member and which allows the member to pivot to follow twisting movement of the seat belt, said attachment means comprising a rod-like first part which extends longitudinally of the member and which defines a first axis about which the member pivots, and a hook-like second part which locates on said mounting, said first and second parts being pivotally interconnected to define a second axis of pivoting transverse of the first axis, the rod-like first part being screw threaded and being connected to the member by means of a screw thread on said member engaged by said rod-like first part so that the rotation of the member about said rod will vary the relative longitudinal positions of said rod-like part and member thereby varying the longitudinal position of the member relative to the first part of the attachment means.

7. A control device according to claim 6 in which the elongate member defines a channel in which the screw threaded rod-like part locates and which houses a screw threaded element engaging said rod-like part.

8. A control device according to claim 7 in which the member is T-shaped with the vertical limb of the T defining said channel and the aforesaid moveable element associated with the horizontal limb.
