Safety belt system

摘要

A safety belt system is described having specially selected highly effective belt components in an especially advantageous arrangement for obtaining a very good cost benefit ratio. A belt tightening motor 100 which is coupled to the rotation of the cardan shaft 18 in the event of an accident actuates via a cable 2 the retraction clamping device 30 as a belt gripping device. Above the latter there is arranged an extremely small self-sensing clamping device 10 which can be activated in the event of an accident and is designed to act as a force-limiting device 12 in conjunction with a specially designed sliding plate 11. The low load makes it possible for the retraction clamping device 30 to be of lightweight construction. This highly efficient belt system is, because of its favourable cost structure, especially well suited for use in small- and medium-range cars. The force-limitation can only commence when a belt has been tightened (pulling down of the retraction clamping device 30) over a minimum distance (e.g. 40 mm). Only then is a locking pin in the connection between the clamping device 10 and the sliding plate 11 pulled out by means of a wire 36. During force limitation (pulling up of the clamping device 10), a predefined slippage occurs in the retraction clamping device 30 from a predetermined load (e.g. 2 KN) onwards. This results in a basic load level for force limitation. In a compact embodiment, the clamping device 10 and the retraction clamping device 30 are [lacuna] on a common mounting plate in a recess 33 in the lower... Original abstract incomplete. <IMAGE>
