Next, Patent Document 1 will be briefly described.
FIG. 14 is an explanatory diagram of a conventional technique (Patent Document 1). In a conventional automobile seat 201, a pipe-shaped main body 204 of a first reinforcing member 203 is disposed under a seat cushion 202, and a side collision occurs. Accordingly, by dispersing the collision load transmitted from the side sill member 205 to the tunnel portion 207 of the floor panel 206, a space for a seated occupant can be obtained.

  FIG. 15 is an explanatory diagram of the prior art (Patent Document 2). In the conventional cabin 221, the actuator 224 of the protection device 223 is disposed in the vehicle seat 222 and is ignited by a sensor at the time of a side collision. Before the vehicle body deformation starts, the bending lever 225 is explosively driven to its extended position, the distances a1 and a2 are eliminated, and the reinforcing elements 226 and 227 are contacted to absorb the collision force, Space can be obtained.

  However, although the automobile seat 201 of Patent Document 1 disperses the impact against the impact applied to the floor panel 206, it is difficult to prevent deformation of the space above the floor panel 206. In particular, when a side impact impact from a door is directly applied to the automobile seat 201 located above the floor panel 206, there is a problem that it is difficult to disperse the impact and it is difficult to prevent deformation of the passenger compartment space near the passenger.

In the cabin 221 of Patent Document 2, it is desirable to arrange the actuator 224 and the bending lever 225 in the vehicle seat 222 in the vicinity of the passenger, and there is a problem that it is difficult to maintain the sitting comfort.
