Problems solved by technology

[0006] However, in the structure that waits for the occupant to sit down and starts the reproduction control as in the prior art, it takes time until the optimum seat support shape is reproduced.
Also, this prevents further improvement in convenience from being realized, so there is still room for improvement in this point

Embodiment Construction

[0020] Hereinafter, an embodiment of a vehicle seat device having an air pressure type seat support function will be described with reference to the drawings.

[0021] Such as figure 1 As shown, a vehicle seat 1 includes a seat cushion 2 and a seat back 3 provided at a rear end portion of the seat cushion 2 . A headrest 4 is provided on the upper end of the seat back 3 .

[0022] As for the seat back 3, both side portions 3a, 3b thereof respectively have a shape swollen toward the front. Furthermore, the seat cushion 2 also has a shape in which both side parts 2a and 2b bulge upward, respectively. Thereby, it is possible to realize and maintain a good sitting posture of the occupant.

[0023] A plurality of air bags 10 ( 11 to 16 ) are provided inside the seat cushion 2 and the seat back 3 . Specifically, on the inner side of the seat back 3, independent air bags 11 (11a, 11b), 12 (12a~12c), 13. In addition, independent air bags 14 ( 14 a , 14 b ) are respectively provid...

Abstract

The vehicular seat device is provided with: a reproduction control unit (60a) configured so as to inflate an air bladder disposed in a seat on the basis of an internal pressure target value; an occupant detection unit (60b) configured so as to detect a seated state, that is, a state in which an occupant is seated on the seat; a body size detection unit (60c) configured so as to detect the size ofthe occupant; and a correction amount calculation unit (60d) configured so as to calculate, on the basis of the size of the occupant, a correction amount (alpha) to be used for correcting the internalpressure target value for a non-seated state, that is, a state in which no occupant is seated on the seat.

Description

technical field [0001] The present invention relates to a vehicle seat device and an air pressure control method of the vehicle seat. Background technique [0002] In a seat device for a vehicle, the seat support shape can be changed by expanding and contracting a plurality of air bags (airbags) provided inside the seat. Usually, in such a seat device, an internal pressure target value is set for each air bag. Furthermore, the seat device is configured to perform reproduction control for reproducing the seat support shape by expanding the air bag based on the internal pressure target value when the vehicle is started. [0003] The internal pressure of the air bag greatly changes depending on whether or not the passenger is sitting on the seat. In other words, in the case where the above-described reproduction control of the seat support shape is performed in a non-sitting state in which no occupant's sitting load is applied, the air bag expands largely. Furthermore, if th...
