ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to a seat device for a motor vehicle, and more particularly to a seat device which is movable to a desired position in the fore-and-aft direction by a seat sliding mechanism.
2. Description of the Prior Art
In a seat device installed in a motor vehicle, a seat body, which is a combination of a seat cushion and a seat back, is usually adjusted in its forward-and-rearward position via a seat sliding mechanism according to the seat occupant's preference.
As illustrated in
FIG. 5
, there is a conventional seat device
10
of so-called a minivan type motor vehicle. This seat device
10
has a seat body
12
that is a combination of a seat cushion
12
a
and a seat back
12
b.
The seat device
10
further has right and left leg members
14
, so that a space
16
is provided between the seat cushion
12
a
and a floor F of the motor vehicle. For example, this space
16
allows a seat occupant on another seat (not shown), which is arranged at the back of the seat device
10
in the motor vehicle, to put his or her feet therein. The seat device
10
further has a pair of seat sliding mechanisms
18
for moving the seat body
12
in the fore-and-aft direction. Each sliding mechanism
18
has a rail construction in which an upper rail (not shown) attached to each leg member
14
is slidably engaged with a lower rail
20
formed on the floor F, thereby allowing the sliding movement of the seat body
12
relative to the floor F. The sliding mechanisms
18
are provided with (1) a locking means (not shown) for locking the seat body
12
and (2) a lever
22
for releasing the locked condition of the seat body
12
. Depending on the position of the seat body
12
in the fore-and-aft direction, the lower rail
20
may be exposed in the interior of the motor vehicle.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a seat device equipped with a sliding mechanism, which is improved in external appearance, spaciousness and rear-seat occupant comfortability.
A seat device according to the present invention comprises the following members: i. A seat cushion disposed on a floor. ii. A pair of first and second front leg members for supporting the seat cushion. Each of the first and second front leg members is fixed to the floor. iii. A third rear leg member for supporting the seat cushion. The third rear leg member is fixed to the seat cushion. iv. A pair of first and second seat slide mechanisms for allowing the seat cushion to slide relative to the floor. Each seat slide mechanism comprises (1) a lower rail fixed to one of the first and second front leg members and (2) an upper rail fixed to the seat cushion and slidably engaged with the lower rail. v. A third seat slide mechanism for allowing the third rear leg member to slide together with the seat cushion relative to the floor.
