Abstract

PURPOSE:To improve a back rest feeling by suitably adjusting the amount of deflection on an energizing means at a part abutted to the back of a sitting passenger in the state of housing the main body of an arm rest inside the recessed part of the main body of a seat back. CONSTITUTION:When a main body 2 of the arm rest is housed in a recessed part 32 of a main body 3 of the seat back, a box 13 is guided closer to a seat back brace 5 while filling a gap between an upper face 10 of the main body 2 of the arm rest and the seat back brace 5 in the position relation of another terminal part 16b of a link bar 16 to a pin 19. Therefore, the feeling of a back rest abutted to a back 62a of a sitting passenger 62 is improved by securing the enough amount of warping in a direction to expand a surface 14 by an energizing means 15 interposed between a bottom part 13a of the box 13 and the surface 14. In the state of protruding the main body 2 of the arm rest from the recessed part 32, the box 13 is made into the same surface as the upper face 10 of the main body 2 of the arm rest in the position relation of the other terminal part 16b of the link bar 16 to the pin 19, and an elbow 62b of the passenger 62 is supported without any incompatibility of sense.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat, and more particularly to a vehicle seat in which an armrest body can be retracted from a seat back.

[0002]

2. Description of the Related Art FIG. 5 and FIG.
(See Japanese Utility Model Laid-Open No. 62-29942). That is, the vehicle seat 50 includes the hinge bracket 5 fixed to the seat back brace 51.
An armrest body 54 that is rotatably supported via pins 53 of 2, 52, and a seatback body 56 in which a recess 55 is formed so as to accommodate the armrest body 54.
And a seat cushion 58 supported by the floor member 57.

[0003]

However, in such a vehicle seat 50, the armrest body 54 is used.
When the box 59 is provided in the armrest main body 54, the amount of bending of the biasing means 61 such as a pad interposed between the bottom 59a of the box 59 and the outer skin 60 is small.
When the occupant 62 is seated in a state in which the vehicle is stored in the recess 55 of the seatback main body 56, the amount of deflection of the biasing means 61 at the portion that abuts on the back 62a of the occupant 62 is small, and the backrest feeling is not good. There is. Therefore, the present invention is for an automobile for improving the backrest feeling by adjusting the amount of deflection of the urging means of the portion that contacts the back of the seated occupant with the armrest body stored in the recess of the seatback body to be an appropriate amount. The purpose is to provide a sheet.

A vehicle seat according to the present invention includes an armrest body rotatably supported by a seatback brace, an armrest body that can be housed, and an upper surface of the armrest body and the seatback brace. A seat back body in which a recess is formed so as to form a gap between the seat back cushion and a seat cushion supported by a floor member, and the armrest body is a rectangular frame, and And a hollow box, a skin that surrounds the frame at a portion excluding the box so as to be flush with the skin of the seat back body when housed in the recess, a back side of the skin, and An urging means disposed between the boxes and configured to urge the outer skin against the boxes in a direction in which the outer skin is inflated and is flexible, and protrudes outside the recess. Connection rod for controlling the box to be flush with the upper surface of the armrest main body and to be in a state of protruding from the upper surface of the main body and filling the gap when the box is housed in the recess. It is characterized by being composed of and.

[0005]

[Operation] According to this structure, when the armrest body is housed in the recess of the seatback body, the box fills the gap between the upper surface of the armrest body and the seatback brace with the connecting rod, and guides in the direction of approaching the seatback brace. Therefore, a sufficient amount of the biasing means interposed between the box and the epidermis bends in the direction of inflating the epidermis, so that the reclining feeling of hitting the back of the seated occupant is improved. When the armrest main body is projected from the recess, the box is flush with the upper surface of the armrest main body, so that the seated occupant's back can be supported comfortably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 4, the vehicle seat 1 includes an armrest body 2, a seatback body 3, and a seat cushion 4. The seat back main body 3 is formed with a recess 32 having a spacer 31 capable of accommodating the arm rest main body 2 and having a gap 11 formed between the upper surface 10 of the arm rest main body 2 and the seat back brace 5. . The seat cushion 4 is supported by the floor member 41.

The armrest body 2 has a rectangular frame 12 and an upper surface 10 with respect to the frame 12.
The seat back body 3 in a state in which it is more retractable and is housed in the hollow box 13 and the recess 32.
The outer skin 14 that surrounds the frame 12 in a portion excluding the box 13 so as to be flush with the outer skin 33, and is disposed between the back surface 14a of the outer skin 14 and the bottom 13a of the box 13 and is the same with respect to the box 13. Biasing means 1 such as a coil spring that is flexible by urging the outer skin 14 in the direction of expansion.
5 and one end portion 16a thereof is rotatably supported by a member 20 fixed to the seat back brace 5 by bolts 17, and the other end portion 16b of the box 13 is provided with an elongated hole 12a formed in the frame 12. And a bracket 18 having one end 18a fixed to the seat back brace 5 by a bolt 17 and the other end 18b rotatably supported on the frame 12 via a pin 19. Consists of. Reference numeral 21 is a lid that covers the opening of the box 13.

According to the structure of this embodiment, as shown in FIG. 3, when the armrest body 2 is housed in the recess 32 of the seatback body 3, the position of the other end portion 16b of the connecting rod 16 with respect to the pin 19 is positioned. In this relationship, the box 13 fills the gap 11 between the upper surface 10 of the armrest body 2 and the seat back brace 5 and guides the seat back brace 5 in the direction of approaching the seat back brace 5.
Since the biasing means 15 interposed between the seat and the occupant 6 secures a sufficient amount of bending in the direction of expanding the skin 14,
The backrest feeling of hitting the second back 62a is improved. Then, as shown in FIG. 4, when the armrest main body 2 is projected from the recess 32, the upper surface 10 of the armrest main body 2 has a relationship with the position of the other end 16 b of the connecting rod 16 with respect to the pin 19. On the other hand, since the box 13 has the same planar shape, the seat 62b of the seated occupant 62 can be supported without any discomfort.

[0009]

As described above, the vehicle seat of the present invention includes the armrest body rotatably supported by the seatback brace, the armrest body that can be housed, and the upper surface of the armrest body and the seatback brace. A seat back body in which a recess is formed so as to form a gap between the seat back cushion and a seat cushion supported by a floor member, and the armrest body is a rectangular frame, and And a hollow box, a skin that surrounds the frame at a portion excluding the box so as to be flush with the skin of the seat back body when housed in the recess, a back side of the skin, and A biasing means that is arranged between the boxes and is flexible to bias the outer skin against the boxes in a direction in which the outer skin expands; And a connecting rod for controlling the box so that the box is flush with the upper surface of the armrest main body and that the box protrudes from the upper surface of the main body to fill the gap in the state of being housed in the recess. When the armrest body is housed in the recess of the seatback body, the box fills the gap between the upper surface of the armrest body and the seatback brace by the connecting rod, and approaches the seatback brace. Since the urging means interposed between the box and the epidermis secures a sufficient amount of bending in the direction of inflating the epidermis, the backrest feeling of the seated occupant's back is improved. It has the practical effect of
