US4371192A — Tension stop for safety belt of the inertia reel …

Claim 1

Independent Claim 217 words

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.

Claim 2

Dependent Claim 217 words

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.

Claim 3

Dependent Claim 35 words

The tension stop of claim 1, wherein the support piece defines a passage comprising, at least at base level, a surface state introducing a coefficient of friction with respect to the material constituting the belt.

Claim 4

Dependent Claim 61 words

The tension stop of claim 1, wherein the support piece cooperates with the blocking piece constituted by a slide block movably mounted in the direction of slide of the belt in the passage and comprising, opposite the inner face of the base of the support piece, a support face inclined convergently towards said face in one of the directions of slide.

Claim 5

Dependent Claim 36 words

The tension stop of claim 3, wherein the support piece defines in its parallel edges two grooves parallel to the direction of slide of the belt and cooperating with complementary projections made on the blocking piece.

Claim 6

Dependent Claim 130 words

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.

Claim 7

Dependent Claim 130 words

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.

Claim 8

Dependent Claim 47 words

The tension stop of claim 5, wherein the support piece comprises at least one transverse edge which 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.
