JPH1146921A - Arm rest for seat - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable to select the best position independently of driver's conformation of body, by attaching an arm rest by a slide means movable in the longitudinal direction to a back rest and an attaching means by a means movable in the vertical direction to the back rest. SOLUTION: A back rest 3 is attached to a seat face to which a head rest is attached slidable in the vertical direction and an arm rest 5 slidable in the longitudinal direction. A first guide rail 11 whose section is formed in a U-shape is fixed to the arm rest 5 and a space to which a second guide rail 12 can be inserted is equipped on its outside. Since the arm rest is slidable in the longitudinal direction, a driver can manually adjust the arm rest at an optimum position matching to his/her conformation of body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat armrest mounted on a side of a backrest of a vehicle seat.

[0002]

2. Description of the Related Art An armrest attached to a backrest of a vehicle seat is known (see, for example, Japanese Utility Model Laid-Open No. 6-72451).

[0003]

However, in the above technique, the vertical position of the armrest can be selected by the driver according to his or her physique and preference, but the position of the armrest in the front-back direction is fixed. Since the length is also constant, the driver cannot select it. Therefore, depending on the physique, the position where the elbow or the arm is placed is inappropriate, and there is a problem that fatigue is increased when driving a long distance.

Further, Japanese Utility Model Laid-Open No. 5-530 and Japanese Utility Model Laid-Open No.
Although the technology disclosed in Japanese Patent No. 40261 is disclosed, none of them relates to the problem of the present application.

Accordingly, an object of the present invention is to provide a seat armrest in which an optimum position can be selected regardless of the physique of a driver.

[0006]

According to the present invention, there is provided a seat armrest attached to a side of a backrest of a vehicle seat, wherein the armrest is provided with a sliding means capable of moving in the front-rear direction with respect to the backrest. The mounting portion of the armrest is attached to the backrest via lifting means capable of vertically moving up and down.

Further, according to the present invention, the sliding means has a first guide rail provided in an armrest and a second end provided with one end fixed to a seat back and slidably provided with the first guide rail. It consists of a guide rail.

According to the present invention, the elevating means includes a pinion gear rotatably provided on a mounting member of the armrest, and a screw rod vertically provided and fixed in a backrest engaged with the pinion gear. And driving means for driving the pinion gear.

Further, according to the present invention, in the armrest of the seat attached to the side of the backrest of the vehicle seat, the first guide rail attached to the armrest and the first armrest attached to the seatback. Sliding means is constituted by the guide rail and the second guide rail engaged with the guide rail, and the second guide rail is fixed to an attachment member attached to the backrest,
A pinion gear is rotatably provided on the mounting member, and a threaded bar that engages with the pinion gear is provided and fixed vertically in a backrest, and a driving means for driving the pinion gear is provided on the armrest.

The present invention is configured as described above, and moves the armrest back and forth by a simple manual operation.
Further, since the driver can be moved up and down, the position can be adjusted regardless of the physique of the driver, and the fatigue of the driver can be reduced.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a seat 1 equipped with an armrest according to the present invention. A backrest 3 is attached to a seating surface 2, a headrest 4 is mounted on the backrest 3 in the vertical direction, and an armrest 5 is connected with a chain line 5a. It is slidably mounted in the front-rear direction as shown by.

FIG. 2 shows the details of the armrest 5. A rod-shaped armrest 5 made of urethane foam and having a rectangular cross section has a first guide rail 11 formed in a U-shaped cross section.
A space 14 is provided outside the first guide rail 11 so that the second guide rail 12 can be inserted therein.

The operation will be described below.

The armrest 5 has a first guide rail 11
Is fixed inside and the space 14 provided outside thereof
The second guide rail 12 having one end fixed to the backrest 3 can be inserted, that is, the armrest 5 can be slid back and forth, so that the driver manually adjusts the armrest 5 to an optimum position according to his / her physique. Can be.

Although FIG. 2 shows a state in which the second guide rail 12 is detached from the armrest 5 for easy understanding of the structure, in practice, the second guide rail 12 is always kept in the armrest 5. It goes without saying that it is designed to be used in a partially inserted manner. FIG. 4 shows another embodiment of the present invention, in which the armrest 5 can be moved in the vertical direction. A shaft 21 is rotatably supported on front and rear ends of an armrest 15 formed of urethane foam. The shaft 21 is provided with a knob 22 at the front end thereof, and a screw portion 21a at the rear end thereof. Is positioned.

The armrest 15 has a threaded portion 21a.
A pinion gear 23 meshing with the pinion gear 23 is mounted, and a screw rod 24 meshing with the pinion gear 23 is vertically mounted on the backrest, and both ends 25, 25 are firmly fixed to the backrest 3 by fixing portions 25, 25. .

Therefore, when the knob 22 is manually rotated, the screw portion 21a provided at the rear end of the shaft 21 is rotated, and the pinion gear 23 attached to the armrest 15 is rotated. The armrest 15 moves up and down along the fixed screw bar 24.

FIG. 5 shows another embodiment in which the first embodiment shown in FIG. 2 is combined with another embodiment shown in FIG. 4 so that the armrest 25 slides in the front-back direction and moves up and down. 1 shows a cross-sectional view of a main part of an embodiment.

A screw rod 24 is attached to the backrest 3 in the up-down direction, and bushes 28, 28 are fixed to a mounting member 27 for attaching the armrest 25 to the backrest 3 so as to be able to move up and down. 24
The mounting member 27 is configured to be able to move up and down along. The mounting member 27 has a second guide rail 1.
The armrest 25 is fixedly engaged with the first guide rail 11 so as to be slidable in the front-rear direction.

Further, a pinion gear 2 meshing with a screw rod 24 is mounted on a shaft 21 having a screw portion 21a at the rear end.
3, the shaft 21 is provided with a pipe 30a slidably provided on the outer periphery thereof, and the shaft 30 is rotated by a knob (not shown) provided at the end of the pipe 30 by a groove 30b and a pin 30c provided in the pipe 30. A driving means for driving the pinion gear is provided.

Therefore, the armrest 25 can be moved in the front-rear direction as in the first embodiment, and the armrest 25 can be moved up and down by rotating the knob as in the other embodiments.

[0023]

The present invention is configured as described above,
Since the armrest can be moved in the front-rear direction and moved up and down by a simple manual operation, the position can be adjusted irrespective of the physique of the driver, and the fatigue of the driver can be reduced.
