Title:
PRETENSIONER
Document Type and Number:
WIPO Patent Application WO/2013/125487
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the weight of a pretensioner by shortening a piston and a wire in the pretensioner. A pretensioner (1) is used in a seatbelt device, and pulls on a seatbelt. A gas supplied from a gas generation device to the interior of a cylinder (10) moves a piston (20) within the cylinder (10). A wire (60) is connected to the piston (20) and the seatbelt, and pulls on the seatbelt when moved by the piston (20). The wire (60) has end parts, both of which are connected to the seatbelt, and a folded-back part (63) that is connected to the piston (20) by a connecting means (51). The connecting means (51) has: a connecting hole (24) that is formed in the piston (20) and through which the folded-back part (63) is passed; and a retaining member (52) that is interposed between the folded-back part (63) and the piston (20), and prevents the folded-back part (63) from separating from the connecting hole (24).
