Problems solved by technology

Therefore, when the position where the convex shape is formed is moved by sequentially expanding and contracting the airbag as described above, there is a problem in that the time required for the movement of the corresponding convex shape depends on the protrusion of the convex shape. change in quantity
In this regard, there is still room for improvement

Embodiment Construction

[0025] Hereinafter, a seat device having an air pressure type seat support function and air pressure control thereof according to an embodiment will be described with reference to the accompanying drawings.

[0026] Such as figure 1 As shown in , a seat 1 for a vehicle 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 at an upper end portion of the seat back 3 .

[0027] In the seat 1 according to the present embodiment, the seat back 3 has a shape in which both side portions 3a and 3b are convex forward. Furthermore, the seat pad 2 has a shape in which both side portions 2a and 2b are convex upward. Therefore, in the seat 1 according to the present embodiment, a good sitting posture of the occupant can be ensured and maintained.

[0028] In the seat 1 , a plurality of air bags 10 ( 11 to 16 ) are provided inside the seat cushion 2 and the seat back 3 . Specifically, in the seat 1 according to the pr...

Abstract

An air pressure control device of a vehicle seat includes: a bulging shape forming unit (50) configured to form a bulging shape on a seat surface (1s) by expanding air bags (10) configured to be provided inside a seat (1); a bulging shape moving unit (50) configured to move a position of the bulging shape formed on the seat surface by each corresponding air bag by sequentially expanding and contracting a plurality of air bags aligned in a direction along the seat surface in an arrangement direction of the air bags; and a pumping capacity adjusting unit (50) configured to increase a pumping capacity of an air pump (31) that pumps air into each air bag as a protrusion amount (X) of the corresponding bulging shape increases when a formation position of the bulging shape is moved. The invention also provides a corresponding air pressure control device of a vehicle seat.

Description

technical field [0001] The present disclosure relates to an air pressure control device for a vehicle seat and an air pressure control method for a vehicle seat. Background technique [0002] In the related art, there has been a vehicle seat device in which an air bag (air bag) provided in the seat is inflated so that the surface of the seat is convex so that the supporting shape of the seat will be Change. For example, the seat device disclosed in JP 03-032943A (reference 1) includes a plurality of air bags which are provided in the seat back against the waist (waist) of an occupant sitting on the seat. at the location. Specifically, the air bags are arranged to be aligned in the vertical direction so as to follow the back surface of the seat back. By sequentially expanding and contracting the air bags along the arrangement direction, the convex shape formed by each corresponding air bag on the seat surface can be vertically moved, that is, the position of the lumbar sup...
