Claims

[Scope of utility model registration request]

Fluid mats that can be expanded or contracted by inflowing or discharging fluid and are embedded in pads at predetermined portions of the seat, body pressure detection means for detecting body pressure at predetermined portions of the seat, and generating compressed fluid. a compressed fluid source, a valve means for controlling the inflow or discharge of the compressed fluid into the fluid mat, and a storage means for storing the appropriate body pressure distribution of the seat;
It is characterized by comprising a control means for controlling the valve means so that the body pressure at a predetermined portion of the seat detected by the body pressure detection means becomes an appropriate body pressure distribution stored in the storage means. Automatic body pressure adjustment seat.
