Abstract
The present invention relates to accessories for safety belts in the form of a tension stop which comprises a support piece defining a passage for a belt, as well as a blocking piece mobile with respect to the support piece and adapted to occupy two positions in which, respectively, it frees the passage or it projects locally therein to tighten the belt. The invention is applicable to safety belts for automobile vehicles.
Claims6
In a tension stop for safety belts of the inertia reel type, comprising, on the one hand, a support piece defining a passage for a belt and, on the other hand, a mobile blocking piece adapted to free the passage completely or to project herein to clamp and tighten the belt against the support piece,
- the support piece is in the form of a "U" comprising a base with two transverse edges and two raised edges defining the passage with the base, said raised edges being provied with means for retaining the blocking piece and guiding said piece towards a position disengaged with respect to the passage or towards a position projecting inside said passage, and wherein at least one transverse edge is inclined with respect to the axis of slide of the belt in the passage to provide support against the perimeter of a slit through which the safety belt passes,
- the blocking piece is constituted by a plate comprising:
- means for cooperation with the retaining and guiding means;
- an inner clamping face opposite and at a shallow angle to the inner face of the base of the support piece for tightening and clamping the belt between the inner face of the base and the clamping face;
- and
- an outer face provided with an actuating member.
A tension stop for safety belts of the inertia reel type, which comprises:
- a support pice in the form of a "U" comprising a base and two raised edges with inwardly turned flanges defining a passage for the belt;
- and
- a blocking piece constituted by a circular plate mounted in the support piece so as to rotate on its axis which is perpendicular to the bottom of the passage, said plate comprising, on its upper face, inclined ramps adapted to cooperate with the inwardly turned flanges on the edges of the support piece and provoking the displacement of said plate on its axis either to engage in or be disengaged from the passage, and having an actuating member on its upper face for rotating the blocking piece on its axis.
