Abstract

An occupant protection device including a pyrotechnical gas generator and a safety valve operating in a temperature-dependent manner and leading to the outside is connected to the gas generator. A sealing element of the safety valve is formed by a pin that includes a pin head, which is inserted from inside into a hole in a wall of a supply element such that the pin head bears against the inner face of the wall. A pin end, which is located on the outer face of the wall and protrudes outwardly through the hole, is plastically reshaped, so that the cross section of the pin end is larger than the cross section of the hole thereby forming a sealing portion which is larger in cross section than the cross section of the hole.
