## Abstract

A seat device includes a massage mechanism configured to massage a first muscle and a vibration generation mechanism configured to administer a vibratory stimulus having a frequency that causes muscle tone to a second muscle, the second muscle being an antagonist muscle of the first muscle.

## Claims

### Claim 1

A seat device comprising:
a first massage mechanism configured to massage a first muscle, the first massage mechanism including a first airbag;
a first vibration generation mechanism attached to a surface of the first airbag, the first vibration generation mechanism is configured to administer a vibratory stimulus to the first airbag, the vibratory stimulus having a frequency that causes muscle tone to the first muscle;
a second massage mechanism configured to massage a second muscle, the second massage mechanism including a second airbag;
a second vibration generation mechanism attached to a surface of the second airbag, the second vibration generation mechanism is configured to administer a vibratory stimulus to the second airbag, the vibratory stimulus having a frequency that causes muscle tone to a second muscle, the second muscle being an antagonist muscle of the first muscle; and
a controller programmed to switch between a state in which the first massage mechanism and the second vibration generation mechanism are actuated together and the first vibration generation mechanism and the second massage mechanism are stopped, the second airbag of the second massage mechanism being contracted when the second vibration generation mechanism is active so that the vibration does not attenuate, and a state in which the second massage mechanism and the first vibration generation mechanism are actuated together and the first massage mechanism and the second vibration generation mechanism are stopped, the first airbag of the first massage mechanism being contracted when the first vibration generation mechanism is activated so that the vibration does not attenuate.

### Claim 2 (depends on 1)

The seat device according to claim 1, further comprising a manual operation unit configured to switch between a state in which the first massage mechanism and the second vibration generation mechanism are actuated together and a state in which the second massage mechanism and the first vibration generation mechanism are actuated together.

### Claim 3 (depends on 1)

The seat device according to claim 1, wherein one of the first muscle and the second muscle is a trapezius, and the other one of the first muscle and the second muscle is a latissimus dorsi.
