Abstract

PURPOSE:To give sufficiently comfortable feeling to passengers by providing an eccentric shaft which is rotation-driven by a driving source through a transmission mechanism, an inner gear which is fastened to the eccentric shaft, a mechanism which axially supports the eccentric shaft rockably through the inner gear and an outer gear which is engaged with the inner gear while having a difference in the tooth number, and a foot holder which is supported by this mechanism. CONSTITUTION:Inner gears 13, 13' are fixed on a pair of supporting bases 12, 12' which are fixed to a rear seat. Outer gears 14, 14' are engaged with the gears 13, 13' with a difference in the tooth number, and the outer gears 14, 14' are rocked by the rotation motion of eccentric shafts 15, 15' which are fastened to these both gears. A gear 16 is fixed to the eccentric shafts 15, 15', and this gear 16 is rotated by a chain 17 through a gear 19 by the rotation of a driving source 18, to rotate the eccentric shafts 15, l5'. A foot holder 21 is fixed to the outer gears 14, l4', and the foot holder 21 rocks by rocking of the gears 14, 14', and the position and direction of the foot holder 21 can be selected optionally. By this method, calves of a passenger are held, and sufficiently comfortable feeling is given to the passenger.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg rest device, which is used in rear seats of automobiles.

0002

[Prior Art] In the rear seats of automobiles, the occupant's feet may be suspended in the air, or even if the legs reach the floor, there is no device to hold them, making it difficult for the occupant to maintain a comfortable posture. is difficult. Particularly when driving long distances, there is a problem in that because the legs are not held in place, sitting fatigue occurs quickly, and the user involuntarily assumes an unreasonable position.

[0003] In order to solve the above problem, for example, Japanese Utility Model Application No. 55-84064 and Japanese Utility Model Application No. 58-
Footrest devices described in Japanese Patent No. 36926 have been proposed. However, both of these footrest devices cut out a part of the seatback of the front seat to create a space, or fold down the seatback to create a footrest.
leg). Even if it were possible to hold the calf, there would be a problem in that the holding position could not be adjusted, and the rear seat occupant's feet would protrude from the hollowed out space in the front seat, making it difficult for the front seat occupant to hold the calf. There is a practical disadvantage that it cannot be used while sitting.

0004

SUMMARY OF THE INVENTION Therefore, in order to solve the above-mentioned problems of the prior art, the present invention aims to hold the calves of an occupant and to make it possible to freely adjust the angle of the holding part. , and its technical challenges.

[0005]

[Means for Solving the Problems] The technical means taken in the present invention to achieve the above-mentioned technical problem are: a drive source; an eccentric shaft rotatably driven by the drive source via a transmission mechanism; The foot holder is rocked by a mechanism that is swingably supported via an inner gear that engages with the eccentric shaft and an outer gear that meshes with the inner gear with a difference in the number of teeth. That's true.

[0006] Based on adopting the above technical means,
The foot holding base allows the occupant's calves to be held at a desired position, and the angle (orientation) of the holding portion can be freely adjusted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a leg rest device according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing the entire leg rest device of the present invention.

In the leg rest device 10 shown in the figure, a pair of support stands 12 are fixed to a rear seat 11.
, 12', inner gears 13, 13' are fixed. Outer gears 14, 14' mesh with the inner gears 13, 13' with a difference in the number of teeth, and an eccentric shaft 1 engages with both gears.
5, 15', the outer gears 14, 1
4' is subjected to a rocking movement in a known manner. Eccentric shaft 15, 15'
A gear 16 is fixed to the eccentric shafts 15 and 1.
Rotate in synchronization with 5'. Chain 17 on gear 16
The rotation of the drive source 18 is transmitted to the chain 17 and the gear 16 via the gear 19, and as a result, the eccentric shaft 15 is rotated. On the other hand, the rotation of the eccentric shaft 15 is controlled by the interlocking rod 2.
0 causes the other eccentric shaft 15' to rotate synchronously. Therefore, the rotation of the drive source 18 is transmitted to both eccentric shafts 15, 15', causing the outer gears 14, 14' to swing. Further, a foot holding stand 21 is fixed to the outer gears 14, 14', and the foot holding stand 21 swings as the outer gears 14, 14' swing. The position and orientation of the foot holder can be arbitrarily selected.

In the above embodiment, the outer gear 14,
14' and a pair of inner gears 13, 13' are used to drive both sides, but the same operation can be obtained with only one side. In addition, 22 and 22' indicate a cover, and 23 indicates a pin, respectively.

0010

[Effects of the Invention] Since the calves (legs) of the occupant can be held by the swingable foot holding table, a sufficient sense of comfort can be given to the occupant. Next, since the swing angle of the foot holding table can be freely adjusted, a sense of comfort can be provided to any occupant depending on the occupant's physique and sitting posture. Further, since the foot holder is configured to rise from the bottom of the seat, the occupant's feet are not caught in the foot holder, which is safe. Furthermore, the device of the present invention can be used even when a passenger is sitting in the front seat. Furthermore, since the mechanical parts are arranged on both sides of the rear seat, the sitting comfort of the rear seat occupant is not deteriorated.
