Arrangement for mounting seat sliding device on vehicle floor

Claim 2

In a motor vehicle, a sliding seat arrangement, comprising: a groove in said vehicle floor; a seat sliding device which comprises two units, each including a stationary rail, a movable rail slidably interlocked with said stationary rail and movement smoothing means for smoothing the movement of said movable rail relative to said stationary rail, one unit of said seat sliding device being tightly received in said groove having a given part of said movable rail projecting upward from said groove; a rug spread on said vehicle floor in a manner to cover said groove, said rug having an elongated slit through which said given part of said movable rail is projected upward, said elongated slit extending along said groove of said floor, so that the sliding movement of said movable rail relative to said stationary rail causes said given part of the movable rail to move in and along said elongated slit; and second means connecting said given part to said seat, wherein the length of said stationary rail is longer than that of said movable rail.

Claim 3

An arrangement as claimed in claim 1, in which said stationary rail has an upper flat surface which is substantially flush with the vehicle floor.

Claim 4

An arrangement as claimed in claim 2, in which said upper flat surface of said stationary rail is formed with a longitudinally extending slit through which said given part of said movable rail passes.

Claim 5

An arrangement as claimed in claim 3, in which the length of said stationary rail is longer than that of said movable rail.

Claim 6

An arrangement as claimed in claim 1, in which at least one of said two units of said seat sliding device is equipped with a position locking device which is located above said rug.

Claim 7

An arrangement as claimed in claim 1, in which said movement smoothing means of said seat sliding device comprises rollers and balls which are rotatably disposed between said stationary rail and said movable rail.

Claim 8

An arrangement as claimed in claim 1, in which said stationary rail and said movable rails are so arranged that even when said movable rail assumes its foremost or rearmost position relative to said stationary rail, the entire movable rail keeping interlocked engagement with said stationary rail.

Claim 9

An arrangement as claimed in claim 7, in which said stationary rail is secured to the bottom of said groove by means of bolts and nuts.

Claim 10

An arrangement as claimed in claim 1, in which said two units of said seat sliding device are identical to each other.

Claim 11

In a motor vehicle, a sliding seat arrangement, comprising: a groove in said vehicle floor; a seat sliding device comprising two units, each including a stationary rail, a movable rail slidingly interlocked with said stationary rail and movement smoothing means for smoothing the movement of said slidable rail relative to said stationary rail, one unit of said seat sliding device being tightly received in said groove having a given part of said movable rail projecting upward from said groove; a rug spread on said vehicle floor in a manner to cover said groove, said rug having an elongated slit through which said given part of said movable rail projects upward; a second means connecting said given part to said seat; and a seat locking device located above said rug, said seat locking device being attached to at least one of said two units and including, a lock plate secured to said stationary rail and projecting upwardly through said elongated slit of said rug, said lock plate having at the upward projecting portion a plurality of lock holes aligned along the axis of said stationary rail, a latch pawl pivotally connected to said given part of the movable rail and a biasing means for biasing said latch pawl in a direction to achieve latching engagement between said latch pawl and the lock holes of said latch plate.

Claim 12

In a motor vehicle, a sliding seat arrangement, comprising: a groove in said vehicle floor; a seat sliding device comprising two units, each including a stationary rail, a movable rail slidingly interlocked with said stationary rail and movement smoothing means for smoothing the movement of said slidable rail relative to said stationary rail, one unit of said seat sliding device being tightly received in said groove having a given part of said movable rail projecting upward from said groove; a rug spread on said vehicle floor in a manner to cover said groove, said rug having an elongated slit through which said given part of said movable rail projects upward; a second means connecting said given part to said seat; and a seat locking device located above said rug, said seat locking device being attached to at least one of said two units and including, a lock plate secured to said stationary rail and projecting upwardly through said elongated slit of said rug, said lock plate having at the upward projecting portion a plurality of lock holes aligned along the axis of said stationary rail, a latch pawl pivotally connected to said given part of the movable rail and a biasing means for biasing said latch pawl in a direction to achieve latching engagement between said latch pawl and the lock holes of said latch plate.

Claim 13

The arrangement of claim 10, in which the latch pawl is pivotally connected through a vertical pivot pin to a horizontal bracket located on said given part of said movable rail.

Claim 14

The arrangement of claim 11, in which said given part of said movable rail is formed with an aperture through which said latch pawl is projected to achieve engagement with the lock holes of the lock plate.

Claim 15

The arrangement of claim 12, in which said elongated slit of said rug is hemmed by an elongated plastic edging frame.
