Claims

[Scope of utility model registration request]

means for detecting body pressure when a passenger is seated;
In a seat having a seat shape adjustment mechanism that corrects detected body pressure distribution to an appropriate value, the seat shape adjustment mechanism is actuated after a sensor detects the seating of an occupant and a predetermined time elapses after the occupant sits on the seat. 1. A seat comprising means for automatically adjusting the shape of the seat surface so as to automatically obtain an appropriate body pressure distribution.
