Abstract

A seat device is provided with: a first air bag expanding and contracting inside a seat surface skin; a holding member for holding the first air bag and movable along the inner surface of the seat surface skin; a drive device for moving the holding member so as to change the arrangement of the first airbag; and a second air bag independent of the first air bag, the second air bag expanding inside the seat surface skin so as to press the seat surface skin to separate the seat surface skin from the first air bag.

First claim

The invention claimed is:

1. A seat device comprising:
a plurality of first airbags inflated and deflated at an inner side of a seat cover;
a holding member that holds the first airbags and is movable along an inner surface of the seat cover;
a driving device that moves the holding member to change positions of the first airbags; and
a second airbag that is independent from the first airbags and inflated at the inner side of the seat cover to press the seat cover and separate the seat cover from the first airbags, wherein
the first airbags are arranged along the inner surface of the seat cover,
the second airbag is arranged between the first airbags,.
the seat device is configured such that the driving device moves the holding member to change positions of the first airbags while the second airbag is inflated at the inner side of the seat cover to press the seat cover and separate the seat cover from the first airbags.

2. The seat device according to claim 1 , wherein the holding member is sheet-like and extends along the inner surface of the seat cover.

3. The seat device according to claim 1 , wherein the driving device includes an actuator that pulls an end of the holding member.

4. The seat device according to claim 3 , wherein the actuator is an air actuator actuated by pneumatic pressure.

5. The seat device according to claim 1 , comprising an urging member that urges the holding member in a direction opposite to a direction in which the driving device moves the holding member.

6. The seat device according to claim 1 , wherein the holding member includes a first holding element and a second holding element that are connected to each other by an elastic member.

7. The seat device according to claim 1 , wherein the driving device is configured to move the holding member in a state in which the first airbags are deflated.

8. A seat device comprising:
a first airbag inflated and deflated at an inner side of a seat cover;
a holding member that holds the first airbag and is movable along an inner surface of the seat cover;
a driving device that moves the holding member to change a position of the first airbag, the driving device including an actuator that pulls an end of the holding member;
a second airbag that is independent from the first airbag and inflated at the inner side of the seat cover to press the seat cover and separate the seat cover from the first airbag; and
a controller configured to:
receive an operation input signal that requests for position adjustment of the first airbag,
in response to receiving the operation input signal, execute an air supply control on the second airbag that separates the seat cover from the first airbag, and
after the seat cover gets separated from the first airbag, execute a drive control on the holding member so that the position of the first airbag changes in accordance with the operation input signal.

9. A seat device comprising:
a first airbag inflated and deflated at an inner side of a seat cover;
a holding member that holds the first airbag and is movable along an inner surface of the seat cover;
a driving device that moves the holding member to change a position of the first airbag; and
a second airbag that is independent from the first airbag and inflated at the inner side of the seat cover to press the seat cover and separate the seat cover from the first airbag,
wherein the driving device is configured to move the holding member in response to the first airbag being deflated and the second airbag being inflated so as to separate the seat cover from the first airbag..

10. The seat device according to claim 1 , wherein the second airbag is arranged in a hole of the holding member.
