First Claim
Patent Images
1. A seat structure comprising:
- a pad that is disposed inside a seat of a vehicle and has elasticity and air permeability;
a housing bag that houses the pad and is adhered to and formed integrally with the pad and is configured to be capable of enclosing air inside; and
air pressure varying means that is communicated with the inside of the housing bag and changes the hardness of the pad by varying the air pressure inside the housing bag.

Abstract
In a seat cushion of a seat, a first actuator supplies air via inside of a communication tube to inside of a air bag in a state where an air valve has been opened by control of a second actuator, whereby air pressure inside the air bag is adjusted, hardness of a pad and in turn the seat cushion is adjusted. Further, after the hardness of the seat cushion has been adjusted, the air valve is closed by control of the second actuator. For this reason, the hardness of the seat cushion can be adjusted at an appropriate hardness with respect to a vehicle occupant.
