Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an ottoman for an automobile seat, which is attached to a front end portion of a seat surface portion of an automobile seat and is used to rest an occupant's feet.

[Prior Art] There is a demand for passengers in the back seat to extend their legs when they are in a car for a long time or when they stop and take a rest. In that case, you can stretch your legs by sitting sideways in the rear seat, but it is not comfortable enough because you cannot use a backrest, and you cannot do so when multiple people are on board.

Therefore, conventionally, an ottoman has been developed that allows a person to take a comfortable sitting posture by putting his / her feet on it without losing the usual sitting posture.

Such an ottoman has a structure as shown in FIG. 6, for example. The ottoman 50 is hinged to the front end of the seating surface portion 51 of the automobile seat and pivots upward (in the state of the chain double-dashed line) to function as an occupant's foot cushion. Therefore, in the ottoman 50, the base end side of the frame 52 is hinged to the front end of the cushion frame 53 by the pin 54, and the cushion body 55 of the cushion frame 53 is extended above the frame 52 to provide the cushion body 56. Has been. And on the base end side of the Ottoman frame 52 gears
57 is fixed, and a latch 58 that meshes with the gear 57 is pivotally attached to the front end of the cushion frame 53 by a pin 59. The latch 58 is adapted to engage with and disengage from the gear 57 by operating the operating lever 60.

To operate the ottoman 50, after pulling up the operating lever 60 in the direction of the arrow A, holding the tip of the ottoman 50 in the stored state and rotating it to a desired angular position, the operating lever 60 is returned and the latch 58 and the gear 57 are rotated. The latch 58 and the gear 57 are disengaged from each other to maintain the usage state.
Rotates downward and is in a substantially vertical storage state with the tip end facing downward.

[Problems to be Solved by the Invention] Such a conventional Ottoman 50 is not only troublesome because the operation for releasing the engagement between the latch 58 and the gear 57 and the operation for rotating the Ottoman 50 itself are troublesome. 50
Since the pivoting operation is performed by gripping the tip of the Ottoman 50 in a substantially vertical storage state, the occupant needs to bend forward and the operation is difficult. In addition, the Ottoman 50 also has a problem in that a rattling occurs at a meshing portion between the latch 58 and the lever 60, and abnormal noise is generated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an ottoman for an automobile seat, which is easy to operate and can be suitably implemented without rattling or noise.

[Means for Solving the Problems] An ottoman for a vehicle seat of the present invention is a frame body attached to a front end of a seat surface portion of a vehicle seat so as to be able to move forward and backward, and a foot hinged to the frame body. A seat cushion part, a spring body linked to the frame body and the foot seat cushion part so as to urge the foot seat cushion part to pivot upward about a hinged portion, and an upward rotation of the foot seat cushion part. It is characterized in that it is composed of a wire which is connected to a foot cushion part and a frame body advancing / retreating means so as to regulate movement and to move in / out as the frame body advances / retracts.

[Operation] Since the present invention is configured as described above, the wire is extended by moving the frame body away from the front end of the seating surface portion of the automobile seat, and the wire is extended by the extended amount. The foot cushion is rotated upward around the hinged portion by the urging force of the spring body. Therefore, the footrest cushion portion automatically obtains a desired angle according to the movement amount of the frame body, and the footrest cushion portion can be used at the above angle by locking the movement of the frame body at this angle.

Further, the wire is shortened by asymptotically moving the frame body to the front end portion of the seat surface portion of the automobile seat, and the shortened footrest cushion portion of the wire rotates downward against the biasing force of the spring body. It moves and is finally held in a stored state.

This link mechanism 7 has a pair of links 7 pivotally supported by pins 8 at the intersections of the upper and lower central portions.
The linking pin 9 is formed by arranging a and 7b. One end of one link 7a is connected to the upper side and the lower side is penetrated through the long hole 2a opened in the frame body 2, and the other end is connected to the upper side and the lower side. The connecting pin 11 pivotally supports the cushion frame 20 with the connecting pin 10, and one end of the other link 7b is connected to the upper and lower sides of the connecting pin 11 through the elongated hole 20a formed in the cushion frame 20, and the other end is connected to the upper and lower sides. It is pivotally supported and attached to the frame body 2 by a connecting pin 12 which is connected to.

A rack gear 13 is pivotally attached to the connecting pin 11 on one end side of the link 7b, and the rack gear 13 is attached so as to mesh with a pinion gear 15 which is appropriately rotated by a motor 14.

Further, the footrest cushion portion 3 is composed of a frame 3a hinged to the frame body 2 with pins 16 and a cushion body 3b attached so as to cover the frame 3a, and has a sufficient space for footrest. Has been formed. For this reason, the footrest cushion portion 3 is rotatable with respect to the frame body 2 around the hinged portion. The pin 16 is composed of a nut 16a and a stepped pin body 16b as shown in FIG. As shown in FIG. 2, the pin 16 has the small diameter portion of the pin body 16b penetrated from the inside of the frame body 2 into through holes (not shown) formed in the frame body 2 and the frame 3a, respectively. The nut 16a is hinged to the pin body 16b from the outer side of 2, and the cushion portion 3 is rotatably hinged to the frame body 2 by placing the foot on it.

The spring body 4 is attached to the hinged portion of the foot cushion portion 3, and the torsion spring shown in FIG. 5 is used. As shown in FIG. 2, this spring body 4 has a coil portion 4c externally inserted into a large diameter portion of a pin body 16b, one end hook portion 4a rests on the cushion frame 3a, and the other end hook portion 4b It is attached to the frame body 2 so as to urge the footrest cushion portion 3 to rotate upward.

Furthermore, the wire 5 has one end on which the cushion frame
It is attached to the protrusion 3c provided on the back surface of 3a, and the other end is attached to the connecting pin 9 on one end of the link 7a. The wire 5 is formed into a substantially L shape by sliding the central portion thereof to the contact portion 2c provided on the frame body 2 and is stretched between the projecting portion 3c and the connecting pin 9, Rotation of the seat cushion portion 3 by the spring body 4 is restricted.

The ottoman 1 is constructed in this way, and its operation will be described next.

In order to use the vehicle seat 6 in a normal use mode, the ottoman 1 is stored in the front part of the seat surface portion 6a. To store the ottoman 1 from the used state, the motor 14 is operated to rotate the pinion gear 15 and the rack gear 13 is moved in the A direction to fold the link mechanism 7 toward the cushion frame 20 side. When the link mechanism 7 is folded, the connecting pins 9 and 11 connected to one ends of the links 7a and 7b move in the respective elongated holes 2a and 20a in the same direction as the moving direction (direction A) of the rack gear 13. To do. By the folding of the link mechanism 7, the ottoman 1 is pulled toward the front end side of the seat surface portion 6a of the seat and is linked.
The wire 5 is also pulled by the movement of the connecting pin 9 of 7a. Due to the pulling of the wire 5, the footrest cushion portion 3 is rotated downward against the biasing force of the spring body 4, so that the upper surface of the footrest cushion portion 3 is in a substantially vertical state and the front portion of the seat surface portion 6a of the seat. Is stored in. Such a state is shown by the solid line diagram and FIG. 2 in FIG. 1 and the storage of the ottoman 1 is completed. In this stored state, the ottoman 1 does not become an obstacle and the occupant can take a normal sitting posture.

In order to change the ottoman 1 from the stored state to the used state, the motor 14 is operated to rotate the pinion gear 15,
This is performed by moving the rack gear 13 in the B direction and extending the link mechanism 7 in a direction away from the cushion frame 20. When the link mechanism 7 is extended, the connecting pins 9 and 11 are elongated holes 2a and 20a which are through holes.
Inside is opposite to the above-mentioned storage direction (B of rack gear 13
Direction). The extension of the link mechanism 7 advances the ottoman 1 in a direction away from the front end of the seat surface portion 6a of the seat, and the wire 5 is pulled out by the movement of the connecting pin 9 of the link 7a. The foot cushion portion 3 is biased by the spring body 4 and pivots upward by the amount of the wire 5 pulled out. By this rotation, a desired angle of the footrest cushion part 3 is obtained, and by locking the movement of the link mechanism 7, the footrest cushion part 3 can be used at the desired angle. Therefore,
The set angle of the footrest cushion portion 3 is automatically determined by the movement of the link mechanism 7. In this use state, as shown in FIG. 3, the occupant seated on the vehicle seat 6 can take a comfortable posture in which the inflatable shin is supported by the foot cushion 3 of the ottoman 1.

According to this embodiment, the footrest cushion portion 3 of the ottoman 1
The operating angle can be set and stored automatically by simply moving the ottoman 1 horizontally, which facilitates the operation.

Further, since the footrest cushion portion 3 is constantly biased to the rotation side by the spring body 4 and the rotation thereof is restricted by the wire 5, it can be suitably implemented without rattling during use and storage.

In the present embodiment, the operability is improved by using the motor 14 that rotates the pinion gear 15, but the pinion gear 15 may be manually rotated.

[Advantages of the Invention] Since the present invention is configured as described above, the use angle of the footrest cushion part of the ottoman can be changed by simply moving the ottoman forward and backward with respect to the front end of the seat surface portion of the automobile seat. Since it can be determined automatically, the occupant does not have to bend forward to rotate the foot cushion, and the operability is extremely good.

Also, since the footrest cushion part of the ottoman is always kept in a tension state by the spring body and the wire, there is rattling,
Moreover, no abnormal noise is generated and it can be preferably implemented.
