Title:
WEBBING TAKE-UP DEVICE
Document Type and Number:
WIPO Patent Application WO/1997/019837
Kind Code:
A1
Abstract:
A webbing take-up device which readily ensures an optimum paid out quantity of webbing at the time of emergency of a vehicle. In a webbing take-up device (10), a webbing take-up shaft (16) is adapted to be locked by an energy absorbing gear (22) at the time of emergency of the vehicle or the like. When a winding load on a webbing (14) becomes great, a force, with which a male thread (46) on the energy absorbing gear (22) is driven into a female terminal (44) of an energy absorbing ring (34), becomes great, so that a force beyond a predetermined value is exerted on a shear pin (50) in a direction of an arrow H, and when the shear pin (50) breaks, rotation of the energy absorbing gear (22) in a direction of tightening is allowed to permit the webbing (14) to be paid out.
