Abstract

A seat system, adapted for a motor vehicle, includes a portable device taken along with a user for sending at least identification information, an on-vehicle front seat, an on-vehicle actuator for actuating the front seat, a keyless control unit and a seat control unit. The keyless control unit communicates with the portable device to lock and unlock door locks when the identification information is authorized, and the seat control unit actuates the actuator to perform a walk-in function for changing a position state of the front seat for a passenger to easily get in a rear seat side compartment according to an operation of the portable device when the authorization is made.

Claims

1. seat system adapted for a motor vehicle comprising:

a portable device that is taken along with a user and is capable of sending at least identification information;

a keyless control unit that is installed on a motor vehicle to communicate with the portable device for locking and unlocking door lock when authorization is judged based on the identification information;

a front seat;

an actuator for changing position state of the front seat; and

a seat control unit that is installed on the motor vehicle to perform a walk-in function for changing the position state of the front seat according to an operation of the portable device so that a passenger can easily get in a rear seat compartment, when the authorization is made.

2. The seat system adapted for a motor vehicle according to claim 1, further comprising:

a request switch provided on the portable device for executing an authentication process, wherein

the seat control unit performs the walk-in function according to the operation of the request switch when the authorization is made.

3. The seat system adapted for a motor vehicle according to claim 1, further comprising:

a request switch provided on a driver'"'"'s-seat side of the motor vehicle for executing an authentication process, wherein

the seat control unit performs the walk-in function of a front passenger'"'"'s seat according to the operation of the request switch when the authorization is made.

4. The seat system adapted for a motor vehicle according to claim 1, further comprising:

a request switch provided on a driver'"'"'s-seat side of the motor vehicle for executing an authentication process, and

a walk-in function setting switch for setting one, to be actuated, of the walk-in functions of a driver'"'"'s seat and a front passenger'"'"'s seat, wherein

the seat control unit actuates the walk-in function of a seat, set by the walk-in function setting switch, according to an operation of the request switch when the authorization is made.

5. The seat system adapted for a motor vehicle according to claim 1, further comprising:

a request switch provided on a driver'"'"'s-seat side of the motor vehicle for executing an authentication process, and

a judging means for judging, based on an operation of the request switch and a state of the motor vehicle, which of the walk-in functions of a driver'"'"'s seat and a front passenger'"'"'s seat is performed, wherein

the seat control unit actuates the walk-in function of a seat, selected based on a judgment result the judging means, according to an operation of the request switch when the auto a request switch provided on a driver'"'"'s-seat side of the motor vehicle for executing an authentication process, and authorization is made.
