Description

Footrest for car seats {omitted}

The present invention can be seated in a seat more comfortable and comfortable in a seat other than the driver's seat to reduce the boarding fatigue even in the long-term or long-term boarding, and can also safely put a simple baggage in front of the seat for a convenient car seat will be.

If you travel long distances by car, you may want to stretch your feet and relax. Buses and trucks with high seats have a higher seat, making it easier to extend the legs, but the situation is different for passenger cars with lower seat heights.

Even if you stretch your legs, the more the angle between your feet and legs is, the more comfortable your feet, ankles and legs are. However, the same is true of the high seat, but the lower the seat, such as a car seat, the greater the angle between the feet and legs when the legs are extended, which is inconvenient.

You can also take your shoes off during a car trip in the spring or summer, when the weather is mild outside. If you step on the floor of your car with your bare feet, it's unsanitary because dirt and dirt from the floor will be transferred to your socks.

Therefore, an object of the present invention can be a comfortable car travel by stretching the legs comfortably, even if you put on socks, safe from dirt and dust and hygienic, when you do not extend the legs can carry a simple baggage safely It is to provide a footrest for a car seat that can also be used as a shelf.

The footrest for automobile seats proposed by the present invention is characterized by being configured to be used under the condition of hiding under the seat so as not to interfere with getting on and off and appearing only when necessary. This is called the launching platform.

As a device for mounting the footrest, the screw type rotates the screw with a small motor to push out the female thread of the bar fixed to the footrest, and pulls the female thread so that the foothold can be hidden under the seat, and the rack with the pinion retracts the rack. Rack-pinion type, and yuan cylinder type, which are intended to be infested. The footrests are flat to allow for simple handholds, and when hidden under the seats, the footrests are folded back so that they do not cling to the bottom of the seats. Even if there is a protruding obstruction, it can easily ride over and is also equipped with wheels to maintain stability even when a load is loaded on the scaffold in the drawn state.

Hereinafter, with reference to the accompanying drawings prepared based on some preferred embodiments will be described in detail.

In Fig. 1, the auxiliary footrest for the vehicle seat includes a footrest 1 and a bar 2, a driving mechanism 3, a footrest 4, a link 5a, b, a wheel 6, and a driving device 7 It consists of).

The footrest 1 has a rectangular shape and is formed flat as an area on which both feet can be placed comfortably. In particular, the side has a flat surface so that the front and rear links 5 installed therein can always maintain a correct posture.

The bar 2 is fixed to the center of the rear side of the footrest 1 so that the footrest 1 can be retracted by the exiting drive device 3 and the female thread is formed at least at the rear end according to the type of the exiting drive mechanism. Or a female thread attached to the rear end of the tube, a rack and a flat tube, which are shown in the form of a screw tube in this embodiment.

The sunken drive mechanism 3 in the example of illustration is a screw type. The screw type outgoing drive mechanism 3 forms a female thread 31 at the rear end of the tubular bar 2, and fastens the screw 32 in a forward and reverse direction by fastening the elongated rotary screw 32 thereon. ) Is mounted so as to be sunk in the front and rear directions, and the footrest 1 is made to stand while rotating forward and backward in place by a drive device 7 which is a manual or small motor. In the illustrated example, the electric screw type is illustrated, and the manual screw may attach a handle to the rear end of the screw 32.

The footrest 4 attaches to the footrest 1 and rests on a foot, and provides a suitable touch and cushion to comfort the foot.

The links 5a and b are for forming a foldable footrest that can fold the footrest 4 low or extend the footrest 4 on the footrest 1, and the front link 5a is short but the rear link 5b is the shaft hole 51. Extend below and attach the wheels 6 to the bottom of the extension. The wheel 6 plays a role of stabilizing the footrest 1 on the floor of the vehicle when the footrest 1 is pushed out, and when a protrusion of the bottom of the vehicle exists when the footrest 4 is moved to an extended state. Do things that make it easier to roll over.

The drive device 7 is electrically connected to a switch and a storage battery not shown, and the switch is attached to a safe position that can be easily operated by hand in a seated position.

Figure 2 shows when the electric screw-type footrest is installed under the passenger seat, rear seat sheet 8 of the vehicle and kept in an unused state. When the electric drive is turned on to rotate the drive device 7 in the forward direction, the screw 32 rotates along the direction and pushes the bar 2. Then, when the footrest 1 reaches a predetermined position, the switch is turned off. Raising the footrest 4 in that position changes to the aspect as shown in FIG.

When the footrest 4 is raised, the wheels 6 reach the bottom of the vehicle to safely support the footrest 1. Thus, the footrest (4) appeared and the person sitting on the seat comfortably put your feet or simple luggage.

In the state where the footrest 4 appeared, this time, when the switch is reversely operated, the driving device 7 is reversed, and the screw 32 is also reversely rotated to attract the bar 2. At this time, the scaffold 1 is drawn under the seat 8 by the bar 2. If the footrest 4 is lifted when the footrest 1 hides under the seat 8, the front part of the seat 8 is caught, and it becomes impossible to hide afterwards. Therefore, it is safe to fold the footrest 4 in advance so that such an accident does not occur.

The footrest 4 folds simply by pressing the back. When the footrest 4 is folded, the front and rear links 5a and b also lie towards it at the same time. In particular, when the rear link 5b is folded, the wheel 6 is lifted from the bottom of the vehicle. At this time, if the wheel (6) is hidden in the inaudible state and there is a shallow inseparable built-in protrusion obstacle on the bottom of the vehicle behind the wheel (6), the peak of the protrusion obstacle from the wheel (6) is caught on the protrusion obstacle The link 5b is divided in the reverse direction when it is unfolded until it passes, so the damage to be received due to the protrusion obstacle is not a concern.

4 shows the above-described screw-type scaffolding drive mechanism 3 replaced with a rack 33 attached to the rear end of the bar 2 and a pinion 34 provided on the seat table. The pinion 34 is a handle attached to one end of the pinion shaft, the electric pinion is connected to the drive device 7 of the small motor capable of forward and reverse rotation of the shaft of the pinion 34 as shown in FIG. By controlling the rotation direction of the pinion (34) is to let the scaffold (1).

6 replaces the scaffolding drive mechanism 3 described above with the hydraulic cylinder 35. The hydraulic cylinder 35 is installed between the rear end of the seat stage and the bar 2. In this structure, when the ram wanders, the scaffold 1 also wanders.

As described above, when the footrest is installed in the front and rear directions under the seat of the car, the foot can be extended and the foot can be put up when traveling or traveling for a long time or a long time by the car, so that the user can feel the fatigue with a comfortable sitting and travel or travel.

It's also hygienic because your feet can be placed comfortably without touching your feet off the floor in a car full of dirt and dust.

In addition, the fact that if you do not want to put a simple luggage can be safely placed adds to the usefulness of the present invention.
