- a seatbelt is provided as a means for preventing an occupant from moving forward due to inertia when a vehicle suddenly decelerates.
- the problem is that the occupant's waist does not work effectively while moving forward while sinking into the seat cushion.
- a cross member such as a pipe is attached to the seat cushion at a position in front of the occupant's waist in a properly seated state in the width direction of the seat cushion. It has been proposed to be distributed over the area. According to this, by receiving the occupant's waist by the cross member, the impact can be absorbed by the deformation of the cross member, and the forward movement can be suppressed.
- a seat cushion raising means is provided at a front portion in a seat cushion, and a movable member is provided which is moved by movement of an occupant's waist during rapid deceleration of the vehicle.

Therefore, it is easy to receive the waist of the occupant who moves forward at the time of sudden deceleration, and the inertial force acting means is disposed above and in front of the support shaft, so that the entire mechanism can be made thin vertically.
- the receiving part Since the change of the moment of inertia due to the swing of the receiving part and the inertia mass part at the time of sudden deceleration that is easy to incorporate into the seat is complementary, the receiving part is used from the start period of the swing to the last stage. It can be moved upward with stable inertial force.
- the receiving portion and the support spring member supporting the lower surface of the seat cushion are connected by an elastic member having a maximum tensile force smaller than an inertia force acting during sudden deceleration, the occupant can sit on the seat.
- the seat cushion is displaced downward while deflecting the support spring member, the receiving portion is pulled downward via the elastic member, so that the foreign object feeling due to the receiving portion at the time of sitting can be reliably eliminated.
- the occupant's movement inhibiting performance during sudden deceleration can be ensured.
- a locking means for preventing the receiving portion from moving downward due to the inertia force at the time of rapid deceleration, the receiving portion moves upward. Since the occupant does not return downward in the retracted state, the effect of receiving the occupant's waist is stably obtained, and the occupant can be reliably prevented from moving forward.
- the lock means includes a lock member urged by the urging means so as to be always in contact with a support member for interconnecting and supporting the receiving portion and the inertial mass portion, and the receiving portion is fixed.
- the lock member is always in contact with the support member.
- the support member and the lock member are arranged so as to be in contact with each other, so that a compact configuration can be achieved.
- the support member also has an axial force that is extended into the receiving portion side and the inertia mass portion side, and the inertial mass portion side has a substantially J-shape when viewed from the side of the vehicle. Vehicle forward position When the lock member is fitted at the bent portion of the J-shaped tip of the support member, the structure that does not require the support member to be provided with an engagement portion is simpler and more compact.
