Seat position adjusting apparatus for vehicle

A seat system for a vehicle, comprising;

• a first slide rail structure and a second slide rail structure adapted to be arranged on a compartment floor of the vehicle so that front ends of the first and second slide rail structures in a front-rear direction of the vehicle outwardly spread in the vehicle width direction and rear ends thereof converge on a vehicle center line in the front-rear direction of the vehicle;
• a first seat and a second seat arranged alongside each other in a vehicle width direction;
• a forward-rearward movement mechanism provided below each of the first and second seats and supported at each of the first and second slide rail structures so that each of the first and second seats is movable along each of the first and second slide rail structures;
• and
• a rotation retaining mechanism provided between each of the first and second rear seats and the forward-rearward movement mechanism, the rotation retaining mechanism rotatably supporting each of the first and second seats and retaining each of the first and second seats at a position where each of the first and second seats faces the same direction as a extending direction of each of the first and second rail structure.

A seat system for a vehicle, comprising:

• a first pair of slide rails and a second pair of slide rails adapted to be arranged on a compartment floor of the vehicle so as to extend in a front-rear direction of the vehicle;
• a first seat and a second seat arranged alongside each other in a vehicle width direction;
• a forward-rearward movement mechanism provided under each of the first and second seats and supported at each of the first and second pairs of slide rails so that each of the first and second seats is movable in the front-rear direction along each of the first and second pairs of slide rails;
• a contact avoiding mechanism provided between each of the first and second seats and the forward-rearward movement mechanism and movably supporting each of the first and second seats in a direction where each of the first and second seats approach each other so that each of the first and second seats does not contact each of rear wheel housings protruding towards a vehicle compartment when each of first and second seats is rearwardly moved;
• and
• a movement restricting mechanism for restricting a rearward movement of each of the first and second seat at a position anterior to a position where each of the first and second seats contacts each of the rear wheel housings when each of the first and second seat is moved backward in a state where each of the first and second seat contacts each of the rear wheel housings, wherein the movement restricting mechanism derestricts the rearward movement of each of the first and second seats in conjunction with an avoidance movement when each of the first and second seats is moved to a state where each of the first and second seats does not contact each of the rear wheel housings.
