Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a footrest for a vehicle seat, which is an improvement of a seat for a vehicle such as a vehicle or an aircraft.

[Conventional technology]

Conventionally, seat seats for vehicles such as automobiles, aircraft, and ships have been constructed with a footrest on the rear of the seat for the seated person on the front seat. If the seats were rotated so that they were facing each other, the footrest had a drawback that the footrest could no longer be used. Therefore, such pivoting seats have generally been constructed so that a footrest is provided on the side of the seat and stored in the lower part of the seat bottom or the like.

[The problem that the idea aims to solve]

However, when setting the footrest on the front side of the seat, it is very difficult to operate this type of footrest from a seated position. Not only does it lack operability because the user has to ask for help, but it also has hygiene problems because the footrest must be held directly in the hand.

The present invention was devised in view of the above-mentioned problems, and it is possible to draw out or store a footrest constructed on the front side of the seat bottom of a stool without touching the footrest, thereby improving operability. It is an object of the present invention to provide a footrest for a vehicle seat which is comfortable and whose angle of use can be easily adjusted.

[Means to solve the problem]

In order to achieve the above object, the footrest of the vehicle seat according to the present invention protrudes or retracts the footrest by the elastic force of the gas spring cylinder, and locks the footrest by the remote locking function of the gas spring cylinder. The protruding angle can be selected, and the footrest is located in front of the seat bottom of a seat for various vehicles, and the footrest is pivoted so that the tip can pivot freely relative to the seat frame at the front end of the seat. A telescopic rod portion of a gas spring cylinder fixed upwardly to the lower part of the seat frame is pivotally connected to the bottom surface of the footrest, and the lower end of the footrest is rotatably raised from the upper surface of the footrest. The main feature is that a footrest bar is pivotally provided, and an unlocking mechanism for the gas spring cylinder is provided near the hand side of the seat via a release wire.

[Effect]

In the above configuration, since the footrest is pivotally mounted on the front side of the seat, the footrest moves with the seat even when the seat is turned, and can be used at all times.

In addition, the footrest can be moved to the operating state or the stored state by the elastic force of the gas spring cylinder, and the displacement can be remotely controlled from your hand, so you can operate the footrest by holding it directly in your hand. It has excellent operability.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a footrest for a vehicle seat according to the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing the front end of the legs of the seat. A seat frame 2 on which the seat bottom 1 of the seat is mounted is supported on the floor by leg frames 3. A back frame constituting a seat back 4 is pivotally installed at the rear end so as to be tiltable or at a fixed angle, and armrests 5 are fixedly installed on both sides of the seat frame 2. The footrest 6 of the vehicle seat according to the present invention is constructed integrally with the seat via hinge brackets 7, 7 protruding from the front frame 2a of the seat frame 2, and includes a footrest plate 8 made of sheet metal. A pin shaft 12 is pivotally mounted in the direction of arrow A via one end of the bottom plate 9 fixedly fixed to the back surface of the seat frame 2 and a hinge pin 10, and is attached to the middle of an erection bracket 11 fixed to the lower part of the seat frame 2. The cylinder proximal end of the gas spring cylinder 13 is pivotally mounted via a pin shaft 14, and the telescopic rod end of the gas spring cylinder 13 is pivotably pivoted near the center of the bottom plate 9 via a pin shaft 14. It consists of a link mechanism that is attached to the The gas spring cylinder 13 is always elastically biased in the direction in which the telescopic rod protrudes, and a locking member 15 (which prevents the sliding of the telescopic rod protruding from the cylinder by changing its position) is provided at the base end of the cylinder. The other end of the release wire 16 connected to the release wire 16 (which can be fixed at an arbitrary position) is connected to the operating end of an operation button 17 fixed to a part of the armrest 5 to form a manual operation mechanism. Reference numeral 18 denotes a footrest bar on which the toes can be placed, which can be accommodated in a groove 8a formed on the surface of the footrest plate 8. Supports fixed at both ends of the footrest bar 18 are provided. The proximal end of the arm 19 is pivotally connected via a hinge pin 21 to a support bracket 20 protruding from the back surface of the tip of the bottom plate 9, so that it swings and projects in the direction of arrow B, and when in the swinging and projecting position. Support arm 1
The bent midsection of 9 comes into contact with a stop pipe 22 installed on the bottom plate 9 to maintain a predetermined angle.

The footrest 6 with the above configuration has a width suitable for use by a single person as shown in FIG. 2, and has an operation button 17 provided on the armrest 5 of each seat.
The seat can be changed into a used or stored state depending on the feet of the person sitting on the seat.

3 and 4 show a seat for two people, the seat on the right side showing the footrest 6 in the retracted state, and the seat on the left side showing the footrest 6 in the used state.

When changing from the storage state to the use state, the footrest 6 can be changed from the right side position to the left side position by pressing the operation button 17. That is, when the operation button 17 is pressed, the locking member 1 of the gas spring cylinder 13 is released via the release wire 16.
5 in the release direction, the gas spring cylinder 13 uses its elastic force to cause the telescopic rod to protrude at a slow speed, causing the footrest 6 to pivot forward about the hinge pin 10. The footrest 6 rotates within the maximum angle range shown on the right seat. When the operation button 17 is released at a desired position during the rotation, the locking member 15 changes from the release position to the stop position, and the gas spring cylinder 13 is rotated. Since the telescopic rod is fixed, the footrest 6 can be fixed at a usage angle position desired by the seated person. If you want to place your feet stably, the foot rest 6 can be lengthened by the amount by which the foot rest bar 18 protrudes by rotating the foot rest bar 18 about the hinge pin 21 in the direction of arrow B. .

Next, when storing the footrest 6, first store the footrest bar 18 in the groove 8a of the footrest plate 8, and then
The seated person can change from the left side posture to the right side posture by pressing the footrest 6 surface with his/her foot while pressing the operation button 17. For an ordinary seated person, since the footrest 6 is in contact with the back side of the second leg, it is possible to press it relatively lightly against the elasticity of the gas spring cylinder 13.

In the above embodiment, an extension type is shown in which a gas spring cylinder is elastically inserted in the direction in which the foot rest is placed in the usage position, but a retractable type gas spring cylinder may be used so that it is automatically retracted when retracted. You can also do that. In addition, in this example, a gas spring cylinder was used for slow operation, but
It goes without saying that the footrest can also be protruded using a general coil spring.

[Effect of idea]

Since the footrest of the vehicle seat according to the present invention is constructed as described above, it can be used regardless of the orientation of the front seat, and when the footrest is set or stored, it can be operated while remaining in the seated position. Moreover, the footrest is characterized by excellent operability in that the footrest does not have to be operated by directly holding it in the hand.

In addition, since the angle of use of the footrest can be adjusted freely, a seat with a seat back that has an angle adjustment function has features such as being able to change and support the footrest to a preferred angle according to the angle. Yes, the practical effects after implementation of this invention are extremely large.
