Abstract

PURPOSE: A vehicle seat is provided to support the pelvis and the disk comfortably by separating the lower part from a backrest and sliding back and forth, to drive for a long time without fatigue, and to prevent the hernia of an intervertebral disk by correcting the backbone. CONSTITUTION: A vehicle seat has a seat cushion(10), and a seat backrest(11). The seat backrest consists of a main body(13) supporting the upper part of the passenger and adjusting an angle, and a supporting body(14) supporting the pelvis and the disk of the passenger and sliding back and forth in the lower part of the main body. A signal from a sensor is transmitted to an electronic control unit, and a motor and a gear driving unit are actuated according to the signal from the control unit. The supporting body is turned with sliding in winding a cable on a pulley to support the waist of the passenger. The passenger is seated comfortably with supporting the upper body of the passenger by the main body and the waist by the supporting body. The supporting body is adjusted according to the shape of the passenger with pressing the pelvis and the disk periodically. The vehicle seat helps to drive for a long time without fatigue, and prevents the hernia of the disk by correcting the backbone.

Description

Seat for automobile {Seat for automobile}

The present invention relates to a car seat, and more particularly, to a seat for a car that can be comfortably supported by the driver's pelvis and disc by making the lower part of the seat back separate from the main body and allowing the front and rear slides separately from the main body. .

In general, the vehicle seat is composed of a seat cushion 10, which is a seating portion, and a seat back 11, which is a lean back portion, as shown in FIG. 1, and adjusts the position of the seat cushion 10 back and forth. By adjusting the angle of the seat back 11 back and forth, a suitable driver posture can be taken.

Particularly, in recent years, the lower back of the seat back 11 has a plate-shaped waist rest (not shown) to allow the back to be comfortably supported.

Reference numeral 12 denotes a lumbar support lever.

However, despite the differences in the structure of the body, namely the position of the waist (the position of the lumbar spine) or the weight of the body (the body pressure distribution on the seat back and the seat cushion), the waist rest of the type currently applied is the same size, Due to its location and construction, there is a limit to applying it to all types of people.

On the other hand, currently widely used waist restraints are increasingly suspected in the effect, the lower back of the human spine, that is, the lower back rest, that is, because the lower back rest plays a role of focusing the body pressure at the disk area, seat seaters can It can be a cause to cause.

Therefore, the present invention has been devised in view of the above, and the drivers who drive for a long time or frequently frequently feel a lot of fatigue due to seat seating problems, and to prevent spinal disorders caused by such a situation. Is there.

In order to achieve the object as described above, in the present invention, by separating the lower part of the seat back from the main body at the same time so that the separated portion can be slid back and forth, the seat back main body to support the weight of the seat occupant upper body and separated lower Is to support the pelvis and disk to comfortably support the pelvis and disk of drivers of various body types.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a vehicle seat comprising a seat cushion 10 and the seat back 11, the seat back 11 can support the load of the seat occupant upper body and the front and rear angle adjustable 13 and It can be supported by the seated pelvis and the disk, characterized in that composed of the pelvis and the disk support 14 slidable back and forth combined with the lower end of the main body (13).

In particular, the pelvis and disk support 14 is characterized in that it is possible to maintain a constant body pressure on the pelvis and disk of the seated seat in a manner of repeating forward and backward in a predetermined cycle in response to a signal by a predetermined sensor means .

This will be described in more detail as follows.

2 is a schematic view showing the configuration of a vehicle seat according to the present invention.

The seat cushion 10, which is a seating part, and the seat back 11, which is a part of leaning the back, are adapted to adjust the position of the seat cushion 10 back and forth or to adjust the angle of the seat back 11 back and forth for a suitable driving posture. In the seat for automobiles to be taken, the seat back 11 is manufactured in a combined structure of the main body 13 located at the top and the pelvis and disc support 14 located at the bottom.

The main body 13 supports the entire weight of the seated upper body while allowing the angle adjustment as before, and the pelvis and the disk support 14 support the seated pelvis and the disc while allowing forward and backward slide rotation. To help.

The pelvis and disk support 14 is capable of position adjustment while the front and rear slide rotation by a predetermined actuator means, by using a characteristic capable of such a front and rear slide rotation, a predetermined sensor is installed in the vicinity of the seat occupant's hip. It is desirable to push to maintain a constant body pressure by the signal of.

At this time, pushing time is about 20 minutes by setting a regular cycle and about 1 minute retreat method can take a big impact on fatigue recovery.

The sensor is preferably installed at the bottom of the center pillar by employing a position sensor.

FIG. 3 shows one embodiment of the actuator means which enables front and rear slide rotation of the pelvis and disc support 14 in the seat according to the invention.

Place the pelvis and disc support 14 on both sides of the bottom of the back frame 15, respectively, and at the top and bottom of the respective shafts 16 on the top and bottom of the pelvis and disc support 14 on the guide plate 17 above and below. It is inserted and guided, and the cable 18 extends from each pelvis and disk support 14 and is fixed to the pulley 20 which is rotated by the motor and gear drive means 19.

Looking at the operating state of the actuator means, a signal by a predetermined sensor means is input to a control means such as an electronic control unit, and rotates when the motor and gear drive means 19 is operated by the output signal of the control means. Since the cable 18 is pulled and wound on the pulley 20, both pelvis and disc supports 14 slide in the direction of the arrow in the drawing, so that the seater's pelvis and disc can be comfortably supported.

On the other hand, when the motor and gear driving means 19 are driven in the reverse direction through the control by the predetermined control means, the pelvis and disk support 14 can be returned to its original position.

Therefore, in the seat of the present invention to which the seat back 11 composed of the main body 13 capable of supporting the upper body of the seated person and the pelvis and disk support 14 capable of supporting the seated body's pelvis and disk is applied. The body weight can be accommodated using the main body 13, and the seated pelvis and the disk portion can be supported by the pelvis and the disk support 14, and the slide operable characteristics of the pelvis and the disk support 14 By using it to maintain a constant body pressure while periodically pushing the seated pelvis and disk of the seat, it is possible to maximize the comfort of the seat.

In particular, since the setting position of the pelvis and the disk support 14, the degree of pressing, etc. can be adjusted according to the body type of the seated person, that is, the position of the pelvis and the disk part, it can be efficiently applied to all drivers of various body types.

As described above, the present invention provides a seat back composed of a main body capable of supporting the seated person's back, and a pelvis and disk support capable of supporting the pelvis and disk, so that the driver can be operated for a long time without fatigue, and the effect of the spinal correction There is an advantage that can reduce the risk of the disk.
