Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seat support device that is movable on a foot surface in front of the seat.

(Prior Art) An automobile seat device is configured as follows, for example. That is, the seat is supported on a seat support surface formed on the floor of the vehicle interior, and a foot surface for the seated person is formed in front of the seat at a position one step lower than the seat support surface. (For example, Utsukai 58-78229
Publication No.).

Further, in the above-mentioned configuration, a wide flat surface (hereinafter referred to as a full-flat surface) that can be used as a bed, for example, may be formed using the sheet on the seat support surface and the foot tread surface.

That is, in this case, the seat can be moved substantially parallel to the foot surface. The seat back of the seat thus moved can be rotated rearward so as to be in a horizontal position on the seat support surface,
This rotation forms a fully flat surface on the seat support surface and the foot tread surface.

(Problem to be Solved by the Invention) By the way, when the seat is moved onto the foot tread surface, the foot tread surface is one step lower than the seat support surface, so there is no bracket for supporting the seat on the foot tread surface. Traditionally, this bracket has been provided separately. However, when the bracket is separately provided in this way, there is a disadvantage that the structure of the seat support device becomes complicated.

Further, when the seat is supported on the foot surface by the bracket, if it is necessary to operate this bracket, it is desirable that this operation be as easy as possible.

(Object of the Invention) The present invention was made in view of the above-mentioned circumstances, and provides a structure in which the seat can be moved onto a foot tread surface that is one step lower than the seat support surface. It is an object of the present invention to provide a simple structure for supporting this sheet on the top and to facilitate operations for this support.

(Structure of the Invention) To achieve the above object, the present invention is characterized by supporting the seat on the foot tread surface by using the components of the locking means for locking the seat on the seat support surface. Another feature is that the posture of the operating lever that causes the locking means to release the locking operation is substantially the same as the posture of the operating lever that causes the seat to be supported on the foot tread surface.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a vehicle interior floor of an automobile, and a front seat support surface 2 and a rear seat support surface 3 are formed on the floor 1 and separated from each other in the longitudinal direction of the vehicle body. A front seat 5 is supported on the front seat support surface 2, and a rear seat 7 is supported on the rear seat support surface 3 via a support member 6.

Both seats above have seat cushion 8.
and a seat back 9 pivotally supported at the rear end of the seat cushion 8 so as to be rotatable back and forth.
Further, the rear seat 7 can be folded onto the seat cushion 8 by rotating forward, and forms a flat surface together with the seat cushion 8 by rotating backward.

Further, a foot surface 11 for a seated person is formed on the floor 1 at a position in front of the rear seat 7 and one step lower than the rear seat support surface 3.

The rear seat 7 is movable in parallel on the foot tread surface 11. When the seat back 9 of the rear seat 7 is rotated rearward on the foot tread surface 11, a fully flat surface is formed by the rear seat 7 on the foot tread surface 11 and the upper surface of the rear seat support surface 3 (see Fig. 1). (Illustrated with dash-dotted line).

The support member 6 that makes it possible to form the above-mentioned full flat surface will be explained in detail below.

A pair of left and right support arms 13, 13 are provided on a seat cushion frame 12 in front of the seat cushion 8 of the rear seat 7 to project rearward. A front leg 15 having a dogleg shape in side view is pivotally supported on the protruding end of each support arm 13.
The rotating end of 5 is pivotally supported by a support piece 16 attached to the rear part of the foot tread surface 11 via a support shaft 16a. Further, the left and right front legs 15, 15 are connected by a stabilizer 17.

Then, the support pin 18 protruding from the middle part in the longitudinal direction of the front leg 15 comes into contact with the lower surface of the support arm 13, so that the support shaft 16a of the front part of the rear seat 7
Further downward rotation around the center is prevented, thereby supporting the front portion of the rear seat 7 on the floor 1.

On the other hand, a cushioning rubber 19 is provided protruding from the rear lower surface of the seat cushion 8, and a rear leg 20 is pivotally supported. The pivoting end of the rear leg 20 projects downward from the lower surface of the cushioning rubber 19 and comes into contact with the upper surface of the rear seat support surface 3.
The rear part of the rear seat 7 is supported on the rear seat support surface 3.

Also provided are locking means 23 which enable the rear seat 7 to be locked onto the rear seat support surface 3. Next, this locking means 23 will be explained.

A locking arm 25 is pivotally supported on each of the support arms 13 via a first pivot shaft 24 . A locking notch 26 is formed at the lower rotating end of the locking arm 25, and the locking arm 25 can be engaged with the support pin 18. This engagement prevents relative movement between the rear seat 7 and the front legs 15,
The rear seat 7 is locked onto the rear seat support surface 3 (shown in solid lines in each figure). Further, a first spring 28 is provided that elastically biases the locking arm 25 so that the locking notch 26 engages with the support pin 18 .

Further, each support arm 13 has a second pivot shaft 2.
an operating lever 30 for disengaging the engagement between the locking notch 26 and the support pin 18 through the lever 9 and releasing the lock of the rear seat 7 on the rear seat support surface 3;
is provided.

The operating lever 30 is composed of a lever main body 31 which is a gripping operation part extending downward from the position of the second pivot shaft 29, and a lock release arm 32 which rotates as the lever main body 31 rotates. Ru. Further, a second spring 33 is provided that elastically biases the lever main body 31 to rotate rearward. Further, the left and right lever bodies 31, 31 are connected by a stabilizer 34.

When the lever main body 31 is rotated forward against the elastic force of the second spring 33, the lock release arm 32 is rotated against the elastic force of the first spring 28 to lock the upper rotation end of the locking arm 25. is pushed, and the engagement between the locking notch 26 and the support pin 18 is released, and thereby,
The locking operation of the locking means 23 is released. In this case, the upper surface of the lock release arm 32 comes into contact with the seat cushion frame 12, and further forward rotation of the lever body 31 is prevented. (Double-dashed line in each figure).

When the rear seat 7 is moved onto the foot tread surface 11, the lever main body 31 is rotated forward as described above to release the locking operation of the locking means 23. Next, when the rear seat 7 is pushed forward, the rear seat 7 is rotated via the front legs 15 and translated onto the foot tread surface 11.

In the above case, the rear seat 7 is supported on the foot tread surface 11 in the following manner.

That is, as shown in FIG. 1, the front part of the rear seat 7 is moved onto the foot tread surface 11 by bringing the rotating end of the lever body 31, which has been rotated forward, into contact with the front end corner of the foot tread surface 11. Supported by Further, the rear part of the rear seat 7 is supported by placing a cushioning rubber 19 on a bracket (not shown) fixed to the floor 1 side.

In the above case, as shown by the one-dot chain line and the two-dot chain line in FIG. It is configured so that the posture of the lever main body 31 supported above is substantially the same.

(Effects of the Invention) According to the present invention, for example, when the seat is moved onto the foot tread surface in order to form a fully flat surface on the floor, the operating lever of the locking means is used to lock the seat onto the seat support surface. Since this seat is supported on the foot tread surface, there is no need for a separate bracket, which was provided in the past to support the seat on the foot tread surface.
Therefore, this seat can be supported with a simple structure.

In addition, since the posture of the operating lever that causes the locking means to release the locking operation is configured so that the posture of the operating lever that causes the seat to be supported on the foot tread surface is almost the same, the unlocking operation of the seat on the seat supporting surface is performed. and the operation for supporting this seat on the foot tread surface can be accomplished in a single operation. Therefore, for example, when forming a fully flat surface, the operation for supporting the seat onto the foot tread surface can be facilitated.
