Abstract: A support unit for a shoulder belt of a safety belt system provided with a rolling mechanism in the form of an integrated component of a seat structure of an airplane seat. A sectional traverse girder is mounted approximately on shoulder level between the side walls of the seat structure of an airplane seat. The transverse girder has a guide slot for the shoulder belt and at least two support webs for the rolling mechanism are clamped in a frictionally engaging manner into the transverse girder.

Abstract: A central lock for multi-point safety belts or safety harnesses includes a housing with several insertion openings distributed over the circumference of the housing. Tongues connected to the belts can be inserted into the insertion openings. A holding plate for holding bolts interacting with the tongues is fixed in the housing. A rotatable release member mounted outside of the housing is provided for axially displacing a release plate against the force of a restoring spring. A mechanism is arranged between the release member and the release plate for transforming the rotary movement of the release member into an axial displacement of the release plate. The mechanism is formed by at least one tilting member arranged between the release member and the release plate which is located on the side of the holding plate facing away from the release member.

Abstract: An energy converter comprises a sleeve with a sleeve channel. A longitudinal groove is configured in the wall of the sleeve channel. A shank of a bolt is introduced into the sleeve channel. An L-shaped deformation member having an arresting leg is introduced into a lateral bore of the bolt shank, wherein then the sleeve leg comes to rest in the longitudinal groove of the sleeve and at the outer surface of the bolt shank. The sleeve and the bolt are thus secured against rotation. The bolt has a hexagonal bolt head, which can be positionally fixed in a matchingly configured aperture in the cheek of the belt fitting. If a predetermined force F acts upon the belt band, the sleeve and the bolt turn relative to one another and the deformation member pulls out of the longitudinal groove while rolling around the bolt shank.

Abstract: A seat belt for a pilot seat or flight attendant seat in an aircraft includes a belt tightener with a reversible energy storage member in the form of a helical compression spring and a rod-shaped energy converter coupled to the energy storage member. The energy converter is at least indirectly connected to a belt member of the seat belt. After the belt member has been tightened and the energy converter has been displaced as a result with an at least partial regeneration of the energy storage member, a cutting chisel penetrates the surface of the energy converter and dampens the movement of the belt member. A renewed activation of the energy storage member after the deceleration phase is prevented by the penetration of a clamping edge of a clamping member in the surface of the energy converter.

Abstract: A safety belt for racing cars and rally sports cars which includes two shoulder belts and a lap belt which can be coupled to the shoulder belt by means of a buckle. The belts are at least indirectly fastened to the car frame. In the two shoulder belts of the safety belt, the kinetic energy resulting from an impact is converted to a different extent and the conversion of the kinetic energy takes place in the shoulder belts within time periods which are shifted relative to each other. As a result, the two shoulder belts are elongated asymmetrically and permit a rotation of the torso of the driver and a subsequent forward displacement of one shoulder relative to the other shoulder.
