Title: Webbing winding device and vehicle
Inventor: NAGATA TOMONORI
IPC: B60R22/40
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a webbing winding device having a simple structure and capable of selecting different force limiter loads at arbitrary timing and a vehicle having the same. SOLUTION: Since a wire 28 whose one end part is fixed on a lock base 16 is inserted into a spool 14, a twist load of a torsion bar 24 and a stroke load of the wire 28 act on a webbing 26 as a force limiter load when the rotation of the lock base is prevented. Moreover, a cutting gear 30 is arranged between the spool 14 and the lock base 16 to cut the wire 28 when the cutting gear 30 is rotated at arbitrary timing, thereby reducing the force limiter load down to the twist load of the torsion bar 24 only. As a result, different force limiter loads can be selected at arbitrary timing by the simple structure.
