Clamping device for motor vehicle safety belts
First Claim
1. A clamping device for a motor vehicle safety belt comprising:
- (a) a housing having a flat base wall along which said belt passes, an oblique front wall and a bottom wall;
(b) a first clamping member located in said housing having a first oblique surface slidably movable along said oblique front wall of the housing and a second oblique surface;
(c) a second clamping member located in said housing having an oblique surface slidably movable along the second oblique surface of said first clamping member and a flat surface along which said belt passes, said oblique and flat surfaces respectively of the second clamping member forming an angle smaller than the angle formed by said first and second oblique surfaces of the first clamping member; and
(d) means for biasing said first clamping member in a direction away from the bottom wall of said housing, whereby said second clamping member is urged by said first clamping member to clamp said belt by said flat surface of the second clamping member against the flat base wall of said housing, when the first clamping member is moved by the belt towards said bottom wall of the housing in response to a predetermined belt tension.

Abstract
A clamping device for a motor vehicle safety belt comprising a housing (2) traversed by the safety belt strap (1) coming from a strap winding device, respectively, from its winding shaft, as well as a first and a second wedge (3,4) arranged in the housing (2). The first wedge (3) forms a deviation member for the strap (1) on the side opposite to the strap winding device, respectively, to its winding shaft, and is provided with two skewed surfaces (12,13) delimiting a sharp angle and differently inclined with respect to the medial plane (16) of the first wedge (3) parallel to the strap (1) in the housing (2). By means of the inclined surface (13) delimiting with the medial plane (16) a larger angle, the first wedge (3) bears against a correspondingly inclined surface (15) of the housing (2) and, by means of the other inclined surface (12), against a correspondingly inclined surface (14) of the second wedge (4). When the strap tension exceeds a predetermined value, the first wedge (3) may move against the action of a spring load (21) in parallel to the strap (1) in the housing (2) along the skewed surface (15) thereof and thereby pushes the second wedge (4) against the strap (1) so as to clamp it in the housing (2).
