Passenger protection apparatus

A passenger protection apparatus comprising:

• a seat with a seat cushion on which a passenger can sit;
• an activation member configured to be activated upward in the seat cushion;
• a first detector configured to detect or predict a collision of a vehicle;
• a second detector configured to detect a sitting state of the passenger sitting on the seat cushion;
• and
• a controller configured to control activation of the activation member, wherein:
• the activation member can change an activation point at which the activation member is activated upward;
• when the first detector detects or predicts a collision of the vehicle, the controller sets the activation point on a basis of the sitting position detected by the second detector, and activates the activation member upward in the seat cushion at the determined activation point, and wherein:
• the activation member comprises a protrusion configured to be activated upward to push a seat surface so that the seat surface is deformed and protruded upward;
• and
• the activation member can change the activation point to change a deformation position at which the seat surface is deformed by the protrusion, and wherein:
• the protrusion comprises a plurality of protrusions, each of the protrusions comprising an airbag capable of deploying upward under the seat surface,
• the protrusions are arranged in the seat cushion in parallel in a front-rear direction of the vehicle, and
• the controller deploys the airbag located in a set deformation position.

• and
• the activation member can change the activation point to change a deformation position at which the seat surface is deformed by the protrusion wherein:
• the protrusion comprises a plurality of protrusions arranged in a seat width direction;
• and
• when the sitting state leans to one side of the seat cushion in the seat width direction, the controller causes the activation member to deform the seat surface at the set activation point from the one side to the other side of the seat cushion in the seat width direction.
