Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) This invention relates to an armrest mounting structure for a vehicle seat provided at, for example, the left and right center of a rear seat cushion.

(Prior Art) Conventionally, as an armrest mounting structure for a vehicle seat of this type, there is, for example, one shown in FIGS. 6 and 7.

The rear seat 1 shown in FIG. 6 is provided with a seat cushion 2 and a seat back 3, and a recess 4 extending vertically and opening forward is formed in the center of the seat back 3. An armrest 5 is provided in the recess 4, and a base (lower end in FIG. 6) of the armrest 5 is pivotally connected to the seat back 2 by a pivot 6.

When the armrest 5 having this configuration is used, the armrest 5 is pivotally moved forward about the pivot 6 so as to be pulled out forward and fall down on the seat cushion 2 as shown in FIG. The upper surface of the armrest 5 in this state becomes an arm support surface 5a on which the arm 7a of the occupant 7 is placed.

(Problem to be solved by the invention) By the way, the armrest 5 in such a use state
The appropriate position of the arm support surface 5a, that is, the appropriate state is the horizontal state. Moreover, in the above-described configuration, the state of the arm support surface 5a is determined by the inclined state of the upper surface 2a of the seat cushion 2.

However, the upper surface 2a of the seat cushion 2 tends to be inclined so that the front part is high and the rear part is low in order to improve the seating performance.

As a result, the arm supporting surface 5a is inclined substantially the same as the upper surface 2a of the seat cushion 2, and the arm 7a on the arm supporting surface 5a is inclined.
Since the angle A becomes smaller, the occupant 7 feels cramped.

Therefore, an object of the present invention is to provide an armrest mounting structure for a vehicle seat that enables a state of an arm support surface when an armrest is used to be always in a proper horizontal state without being influenced by the inclination of the upper surface of a seat cushion. Is what you do.

(Means for Solving the Problems) In order to achieve this object, the present invention relates to an armrest mounting structure for a vehicle seat in which an armrest is disposed on a central rear portion of a seat cushion so as to be able to fall around a base end. The seat cushion is constituted by a middle cushion corresponding to the armrest and left and right end cushions sandwiching the middle cushion, and the armrest is attached to a rear end of the middle cushion so as to be able to fall forward around the base end. In addition, the middle cushion has an armrest mounting structure for a vehicle seat mounted between the end cushions so that a rear end portion can be displaced upward by pressing a front portion side downward. Is what you do.

(Operation) According to such a configuration, when the front portion of the upper surface of the armrest is higher than the rear portion in a state where the armrest is laid down on the middle cushion, the arm is placed on the armrest, and When the front portion is pressed downward by the arm, the front portion of the middle cushion is pressed downward by the armrest, and the rear portion of the armrest and the middle cushion are integrally displaced upward, so that the upper surface of the armrest is in an optimal horizontal state. Become.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

In FIG. 5, reference numeral 10 denotes a rear seat of an automobile, 11 denotes a seat cushion of the rear seat 10, and 12 denotes a seat back of the rear seat 10.

A recess 13 extending vertically and opening forward is formed on a central rear portion of the seat cushion 11, and an armrest 14 is provided in the recess 13. This armrest
As shown in FIGS. 1 to 4, a slit 15 is formed in a side wall 14b of a base end portion (lower end portion in the figure) 14a of the 14 in a thickness direction (a front-rear direction in the drawings) as shown in FIGS. Also, this side wall 14b
A semi-circular catch bracket 16 disposed at one end (rear end in the figure) of the slit 15 is embedded in the slit 15 and an arc-shaped guide slit 17 is formed concentrically with the catch bracket 16. Such a structure of the side wall 14b is provided also on the other side wall (not shown) of the armrest 14.

A support shaft 18 that passes through the slit 15 of the armrest 14 is fixed to a frame (not shown) of the seat back 12. Thereby, the armrest 14 is provided so as to be able to fall forward around the base end portion 14a, that is, the support shaft 18. The seat cushion 11 includes a middle cushion 19 corresponding to the armrest 14, and left and right end cushions 20, 20 sandwiching the middle cushion 19.

The middle lower part of the middle cushion 19 is a support shaft extending left and right.
The end cushions 20, 20 are rotatably held by frames (not shown) of the end cushions 20, 21. Also, in this cushion 19
Is formed with a step 22 extending from the front end to below the support shaft 21. In this manner, the middle cushion 19 is mounted between the end cushions 20 so that the rear end can be displaced upward by pressing the front side downward. The pivotal position of the support shaft 21 is preferably set at the approximate center of the middle cushion 19 in the front-rear direction and at the front and rear thereof.

Further, arms 23 project upward from both sides of the rear end of the middle cushion 19, and a guide piece 24 engaged with the guide slit 17 is integrally provided at the upper end of the arm 23. I have. Thereby, the armrest 14 is mounted on the rear end of the middle cushion 19 so as to be able to fall forward around the base end 14a.

Next, the operation of the armrest mounting structure for a vehicle seat having such a configuration will be described.

According to such a configuration, when the front portion of the upper surface of the armrest 14 is higher than the rear portion in the state where the armrest 14 is laid down on the middle cushion 19 as shown in FIG. When the occupant's arm is placed on the armrest 14 and the front portion of the armrest 14 is pressed downward by the arm, the front portion of the middle cushion 19 is pressed downward by the armrest 14. This allows the armrest 14
And the middle cushion 19 is rotated about the support shaft 21, and the rear portion is integrally displaced upward as shown in FIG.
The upper surface 14c of the armrest 14 is in an optimal horizontal state.

(Effects of the Invention) As described above, the present invention has a configuration in which the front cushion is pressed downward, so that the middle cushion is mounted between the end cushions so that the rear end can be displaced upward. The state of the arm support surface at the time of use can always be in a proper horizontal state without being influenced by the inclination of the upper surface of the seat cushion.
