<p>To set the limit load applied to seatbelts more flexibly and variously depending on the situation of emergency.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">When the gas generated from a gas generator (25) in a crash is introduced into a pressure chamber (24), a pressure piston (22) and a pressure rod (23) move to the right, so that the end (23a) of the pressure rod (23) comes into pressure contact with a seatbelt (3). The seatbelt (3) is pushed between the pressure rod (23) and a belt receiver (30). At that time, the movement of the pressure piston (22) is controlled by a piston-movement limit member (26) depending on the situation of emergency, thereby varying the pressure to the seatbelt (3). Thus, the limit load applied to the seatbelt (3) can be set flexibly and variously depending on the situation of emergency.
