Abstract

PURPOSE:To provide sufficiently comfortable feeling by holding both calves and ankles of a passenger on a rear seat of an automobile by a method wherein an auxiliary base is provided on a foot rest, and the auxiliary base is constituted in such a manner that it is stretchable from the foot rest. CONSTITUTION:An auxiliary base 14 is slidably fitted on a foot rest 12, and a driving source 15 is fixed on the foot rest 12. The rotation force of the driving source 15 is transmitted to a screw 17 through a reduction unit 16, and a nut 19 which is wrapped by a cushion 18 is screwed on the screw 17. The cushion 18 and the nut 19 are fixed on the auxiliary base 14 by a bracket 20, and the nut 19 moves forward and backward relatively to the foot rest 12 by the rotation of the screw 17, and therefore, the auxiliary base 14 moves forward and backward to the foot rest 12. By this method, both calves and ankles of a passenger on a rear seat of an automobile can be held, and sufficiently comfortable feeling can be given.

[Detailed description of the invention]

0001

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

0002

2. Description of the Related Art Conventionally, various footrests and the like have been devised in the rear seats of vehicles so that rear seat occupants can have a comfortable posture. For example, the one described in Japanese Utility Model Application Publication No. 60-87828 has a footrest that comes out from the seat back of the front seat, and the one described in Japanese Utility Model Application Publication No. 55-8406
In the system described in Publication No. 5, the center portion of the seat back of the front seat is hollowed out, and the feet of the rear seat occupant can be placed in the hollowed-out space.

However, in both of the above conventional techniques, it is not only difficult to ensure sufficient comfort when sitting for long periods of time, but also the front seat cannot be occupied by the passenger. Or, when you get in the car, the position of the front seat makes it impossible to make sufficient adjustments.

SUMMARY OF THE INVENTION Therefore, in order to solve the problems of the prior art described above, the present invention aims to solve the technical problem of providing a sufficient sense of comfort to rear seat passengers. shall be.

[0005]

[Means for Solving the Problems] The technical means taken in the present invention to solve the above-mentioned technical problems is a leg rest device having a structure in which a footrest is pivotally supported in a swingable manner. The footrest has a slidable auxiliary base, and the auxiliary base is configured to extend and contract with respect to the footrest. In particular, the auxiliary stand is configured to expand and contract using a drive source, a reduction gear, a screw, and a nut screwed onto the screw.

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.

The leg rest device 10 has a footrest 12, a driving source, a transmission mechanism using gears or a chain, an eccentric shaft driven to rotate, a known inner gear that engages with the eccentric shaft, and a difference in the number of teeth from the inner gear. The footrest 12 is made swingable relative to the rear seat 11 by a mechanism 13 (detailed in a separate application filed by the same applicant) that is swingably supported via a known outer gear that meshes with the footrest. will be placed. That is, footrest 1
2 rises while rotating due to the action of the mechanism 13.

[0008] The footrest 12 has an auxiliary base 14 slidably attached thereto.
are fitted, and the drive source 15 is fixed to the footrest 12. The rotational force of the drive source 15 is transmitted to a screw 17 via a reduction gear 16, and a nut 19 surrounded by a cushion 18 is screwed onto the screw 17. The cushion 18 and nut 19 are fixed to a bracket 20, and further fixed to the auxiliary stand 14 via the bracket 20. As the screw 17 rotates, the nut 19 moves back and forth relative to the footrest 12, so the auxiliary stand 1
4 moves in the front and back direction with respect to the footrest 12.

[0009]

As explained above, the leg rest device of the present invention has an auxiliary base on which the footrest can slide, and the auxiliary base is configured to expand and contract with respect to the footrest. It can hold both the calf (leg) and the ankle. Therefore, it is possible to provide the rear seat occupant with a sufficient sense of comfort. The rotation angle of the footrest can be freely adjusted relative to the rear seat, and the length of the footrest can also be changed freely, so it can be adjusted to suit the physique of the occupant, whether large or small. It can be used in any sitting position. Furthermore, since the footrest is configured to rise from the bottom of the rear seat, there is no risk of the occupant's feet getting caught in the footrest, making it safer. Moreover, even when the rear seat occupant is using the leg rest device of the present invention, the occupant can also sit in the front seat. Furthermore, since the footrest has a two-stage configuration, it has the practical effect of being easy to store.
