The seat surface of general car seats is not adjustable in front and back length, so the seat surface is too long and difficult to drive, especially for petite women, and conversely, for large men. There were also complaints that the seat was too short. Conventionally, it has been proposed that the seat surface is divided into front and rear parts, and the front and rear length of the seat surface can be adjusted by pulling out the front seat surface. It was uncomfortable to use because there was a gap between it and the rear seat.

Furthermore, a pair of left and right brackets 8, 8 and a pair of guide rails 9, 9 are fixed to the upper rail 5, and these are provided at the front and rear ends of the upper rail 5, respectively, but their front and rear positions are different from those in the drawings. It may be the other way around. Reference numerals 10 and 10 denote a pair of left and right links, one end of which is pivotally mounted 11 to the bracket 8, and the other end pivotally mounted 13 to the seat cushion pan 1 via a stay 12. 14,14
is a shoe that can move back and forth by engaging with the guide rails 9, 9, and is fixed to the seat cushion pan 1 via stays 15, 15.

A nut 16 is fixed to a connecting member 17 fixed between the guide rails 9, 9 and the upper rails 5, 5, and the nut 16 is attached to a bracket 18 fixed to the cushion pan 1, which can rotate but not move forward or backward. A threaded rod 19 is screwed onto the seat frame 1, and when the threaded rod 19 is turned, the cushion pan 1 can be moved back and forth relative to the seat frame 3 integrated with the nut 16, that is, the upper rail 5. Note that the mechanism for moving the seat cushion pan back and forth relative to the seat frame is not limited to the screw and nut mechanism shown in the drawings. The position may be fixed by a latch mechanism. Note that a supporting body such as a rolling roller may be used in place of the shoe 14.

Next, to explain the operation, in order to move the seat surface backward and shorten it, for example, by turning the threaded rod to the right, the threaded rod 19, together with the seat cushion pan 1, moves to the right with respect to the upper rail 5 in FIG. Moving. In this case, the shoe 14 is guided by the guide rail 9 and moves rearward, and the link 10 is moved to the pivot point 1.
The seat 2 is tilted so that the three points are rearward, and as a result, the seat 2 is supported by the link 10 and the guide 9 and smoothly moves rearward in a substantially horizontal state. Also sheet 2
To move forward, turn the threaded rod 19 to the left, and it will move forward by the reverse operation.

Since the present invention is configured as described in detail above, when the seat cushion pan is moved back and forth by moving the body back and forth while seated, the seat cushion pan is guided by the tilting link at one end, and the other end is guided by the inclined link. Since the seat is guided by the guide rail via the support, it can move smoothly back and forth while always maintaining a nearly horizontal state, and the length can be easily adjusted back and forth without creating a gap on the seat surface.

Previously, in Japanese Utility Model Application Publication No. 57-50247, a vehicle seat with adjustable cushion length has been proposed, but in this case, the seat cushion was connected to a seat back over almost the entire length of the seat cushion on the side of the seat. A main rail is provided, and an upper rail, which is approximately the same length as the main rail and slides back and forth while engaging with the main rail, is fixed to the side surface of the seat cushion. Therefore, the conventional vehicle seat is
A main rail and an upper rail that are the same length as the front and rear length of the seat cushion are required, but the weight of the rails is extremely large due to the long rail length.
This caused problems such as the weight of the vehicle increasing accordingly.

In the present invention, one end of a seat cushion pan is pivotally connected to each other end of a pair of links, one end of which is pivotally connected to a seat frame, and the other end of the cushion pan is
The pair of guide rails fixed to the seat frame are each fixed to sliding or rolling supports so that the cushion pan can be moved back and forth with respect to the seat frame. Compared to conventional very long main rails and top rails, the guide rail only needs to be very short in length, just enough to move the seat cushion back and forth, so the weight of the guide rail is very small and the structure is very simple. It has several excellent advantages.
