Claims

[Scope of utility model registration request]

A support strength control circuit 43 that adjusts the support force of the side support from the support force sensor 7 to a preset support force based on an operation command signal from the operation switch section 8, and a vehicle speed sensor 9.
The vehicle speed information signal from the traveling speed detector 45 and the vehicle speed sensor 9 closes the gate 46 when the support force reinforcement is not required and opens the gate 46 when the support force reinforcement is required. a response centrifugal force setting device 48a that sets the response start centrifugal force of the support force according to the response centrifugal force setting; a centrifugal force sensor 10a that outputs the centrifugal force generated when the vehicle runs on a curve as a centrifugal force information signal; When the centrifugal force information signal passing through the open gate exceeds the response start centrifugal force set by the travel speed detector 48a, the support strength control is performed using correction data for correcting the support force. An automatic side support adjustment device for a vehicle seat, comprising a level determiner 50 outputting to a circuit 43.
