Abstract
A submarine preventing mechanism is arrange inside a seat. The submarine preventing mechanism is provided with brackets attached to a cushion flame, links, and a submarine preventing body supported by the links. The links have first ends rotatably supported by the brackets by means of support shafts, respectively. The links have second ends located at a lower level than the support shafts. The submarine preventing body includes a first rod, a second rod, and a gas generator for generating a gas with which the second rod is pulled into the first rod at the time of a vehicle collision. If the vehicle collision occurs, the gas generator burns, generating a gas. In response to this, the second rod is pulled into the first rod. Accordingly, the links are rotated upward, raising the submarine preventing body.
