Definitions
- the present invention relates to a seat belt retractor with load limiting.
- the seat belt retractor shown in Fig. 1 comprises a cylindrical retractor spool 1 mounted for rotation about a spindle 9 concentric with the spool axis in a frame 21 to wind in and payout seat belt webbing.
- the spool 1 is shown in more detail prior to load limiting.
- the spool 1 has an axis of rotation 11 and a winding drum in the form of a spiral formation 5 at one end of the spool.
- the winding drum is formed as a spiral so that the angle of the coil of wire changes gradually. This has the advantage of producing a relatively flat load-displacement graph, i.e. of absorbing the load applied to the webbing, in a crash situation, with the maximum efficiency.
- the wire may be performed from steel with a first straight portion or a slight curve followed by one or more coils and followed by a second straight portion.
- the pin can then be inserted through the coils.
