Abstract
An anchoring arrangement of an end point or deflection point of a safety belt, especially in motor vehicles, under interposition of a spring at a fixed vehicle part; the spring is installed prestressed in the sense of a tightening of the belt band and is blocked in the normal driving operation in this position while the blocking is released by a force peak exceeding the prestress force of the spring which occurs at the beginning of an accident at the belt band.
Claims19
An anchoring arrangement of an end or deflection point of a safety belt, at a fixed structural part fixed relative to the vehicle under interconnection of a spring means, characterized in that the spring means is installed prestressed in the sense of a tightening of the belt band and is blocked in the prestressed position during normal driving operation, and in that the blocking is released by a force peak with occurs at the beginning of an accident at the belt band and exceeds the prestress force of the spring means, characterized in that an eye means cooperating with the belt band is displaceably guided in a fitting means fixed relative to the vehicle, the fitting means having a bent-off free end which in normal operation blockingly engages in a recess of the eye means, and in that the spring means is supported both at the fitting means as also at the eye means.
An anchoring arrangement of an end or deflection point of a safety belt, at a fixed structural part fixed relative to the vehicle under interconnection of a spring means, characterized in that the spring means in installed prestressed in the sense of a tightening of the belt band and is blocked in the prestressed position during normal driving operation, and in that the blocking is released by a force peak which occurs at the beginning of an accident at the belt band and exceeds the prestress force of the spring means, characterized in that a spring means extending transversely to the tensional direction of the belt band is supported at a fitting means relative to the vehicle in the tensional direction in two points, in that an eye means cooperating with the belt band is operatively connected with the spring means between said support points, and in that on the side of the spring means opposite the two first-mentioned support points, a third support point is provided blocking the spring means in normal operation opposite the tensional direction of the belt band.
An anchoring arrangement of an end or deflection point of a safety belt, at a fixed structural part fixed relative to the vehicle under interconnection of a spring means, characterized in that the spring means is installed prestressed in the sense of a tightening of the belt band and is blocked in the prestressed position during normal driving operation, and in that the blocking is released by a force peak which occurs at the beginning of an accident at the belt band and exceeds the prestress force of the spring means, characterized in that the recess as also the free end of the fitting means engaging into the recess are provided with bevelled surfaces cooperating in the sense of a reduction of the release force.
An anchoring arrangement of an end- or deflection-point of a safety belt comprising:
- (a) a fitting fixedly mountable to the vehicle body;
- (b) a safety belt attachment member for receiving a safety belt and displaceably arranged relative to said fitting;
- (c) spring means interconnecting said fitting and attachment member;
- (d) releasable engagement means for retaining said attachment member in a normal driving position prestressing said spring means, said engagement means being disengageable upon applicantion of a force in excess of the prestressing of the spring means for enabling shifting of said attachment member from said normal driving position under prestress relieving movement of said spring means to thereby tighten said safety belt.
