Description

  The present invention relates to an armrest structure for a vehicle seat, and more particularly to an armrest structure that can be used or stored by rotating the armrest with one end thereof as a fulcrum.

  The vehicle seat includes a type in which a second-row seat disposed in the middle of the traveling direction of the vehicle is divided into three in the lateral direction perpendicular to the traveling direction. That is, in this type of sheet, the center sheet is detachably provided between the two side sheets arranged in the lateral direction. When the center sheet is disposed between the side sheets, the second row seat is used for three seats, and the second row seat with the center seat removed is used for two seats. The space between the side sheets when the center sheet is removed is used as a space for a walk-through connecting the first row sheet and the third row sheet.

As for the armrest structure of the seat that is divided into three in the lateral direction of the vehicle as described above, for example, a technique disclosed in Patent Document 1 is known. In this technique, two independent armrests are rotatably provided on the back side of the seat back in the center seat disposed between the side seats. And when using the seat for two-seaters, the seat back of the center seat is folded forward and superimposed on the seat cushion, and if necessary, both armrests are individually placed in parallel with the back of the seat back knock down. As a result, two independent armrests can be used according to the needs of both seats. In addition, the seat can be used for three seats by raising the two armrests together and then raising the seat back of the center seat.

  In the technique disclosed in Patent Document 1, both armrests in a state where the seat is used for three-seaters are housed on the back side of the seat back of the center seat. For this reason, it cannot be said that the armrest at the time of accommodation is utilized effectively.

  The present invention is intended to solve such problems, and an object thereof is to enable effective use of an armrest during storage.

The present invention is for achieving the above object, and is configured as follows.
The armrest is held in parallel state the seating face of the seat cushion at the time of use, its opposite end an end portion of the seat back side as a fulcrum is by rotating so that the upper portion of the seat back, use The armrest structure of the vehicle seat that can be stored in a state where the lower surface of the armrest is aligned with the front surface of the seatback, the vehicle seat being arranged in two lateral directions orthogonal to the traveling direction of the vehicle A detachable center sheet is provided between the side sheets. The armrests are respectively provided at the end portions on the center seat side in both side seats. The lower surfaces of both armrests in use are set in a shape that forms at least a part of the side support in the seat back continuously with the seat back surface of the center seat when the armrests are stored.

Thus, since the lower surface of the armrest in use constitutes at least a part of the side support in the seat back when the armrest is stored, the armrest can be effectively used when stored.
In addition, since both armrests are provided on the two side seats, respectively, the center seat located between these side seats can be reduced in size and weight, and can be easily detached. In addition, the seat back of the center seat can be widely used instead of being small when seated on the center seat because at least a part of the side support is constituted by both armrests when stored.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is an external perspective view showing a vehicle seat. The seat shown in this drawing is the second row seat arranged in the middle of the seats arranged in three rows along the traveling direction (front-rear direction) of the vehicle. This second row seat is divided into three in the lateral direction (left-right direction) orthogonal to the front-rear direction, and a center seat 30 is detachably provided between the two side seats 10 arranged on the left and right. That is, the second row sheet with the center sheet 30 disposed between the side sheets 10 can be used for three-seater use, and the second row sheet with the center sheet 30 removed is It is for two people.

  As is well known, the basic structure of the both side seats 10 includes the seat back 12 and the seat cushion 14 individually. Similarly, the center seat 30 includes a seat back 32 and a seat cushion 34. However, since the center seat 30 is attached and detached between the side seats 10, a reduction in size and weight is required, and the lateral width is set to about half that of the side seats 10. Note that the space between the side sheets 10 when the center sheet 30 is removed is used as a space for walk-through between the second row sheet and the third row sheet (not shown).

  FIG. 2 is an enlarged perspective view of the central portion of the second row sheet. 3 is a cross-sectional view in the direction of arrows AA in FIG. As is apparent from these drawings, the armrest 20 is provided between the side surface of the seat back 12 of the side seats 10 on the side of the center seat 30 and both side surfaces of the seat back 32 of the center seat 30. These armrests 20 are used by the occupants of both side seats 10 as armrests according to their preference, and the use state of the armrest 20 located on the left side of FIGS. Yes. As shown by the phantom lines, the armrest 20 in use is held in a state of protruding forward in parallel with the seat surfaces 15 and 35 of the seat cushions 14 and 34 in the side seat 10 or the center seat 30. A seated person of both side seats 10 uses the elbows on the inner side (center seat 30 side) on the upper surface 24 of each armrest 20 in this state.

  The two armrests 20 can be individually rotated with the end portions 22 of the side seat 10 or the center seat 30 on the side of the seat back 12 and 32 being used as fulcrums during use as indicated by the phantom lines in FIG. That is, the end portions 22 of both armrests 20 are rotatably supported by the individual support shafts 28 with respect to the frames (not shown) in the seat backs 12 of both side seats 10 (FIG. 2). However, the rotation in the direction in which the end 23 on the side projecting forward in both armrests 20 in use is lowered is naturally restricted, and the function as an armrest is maintained.

  By rotating both armrests 20 in use around the axes of the individual support shafts 28 so that the respective end portions 23 are located above the seat backs 12 and 32 of the side seats 10 or the center seat 30, The armrest 20 is in the storage state shown in the drawing. That is, both armrests 20 are accommodated in a space between the side surface of the side seat 10 on the side of the center seat 30 on both side seats 10 and both side surfaces of the seat back 32 on the center seat 30. At this time, the lower surface 25 when both armrests 20 are used is in a state of being continuous with the surface 33 of the seat back 32 of the center seat 30 (see particularly FIG. 3). Further, both armrests 20 are restricted from further rotation and are held in the storage state shown in the drawing.

  As described above, the lower arm 25 of each armrest 20 during storage is continuous with the surface 33 of the seat back 32 in the center seat 30 and constitutes a part of the side support of the seat back 32. Therefore, the armrest 20 at the time of storage can be used effectively, and the center seat 30 when using the second row seat for three persons can be widely used. Further, since both armrests 20 are supported by the seat backs 12 of both side seats 10 and separated from the center seat 30, the center seat 30 that is attached and detached as described above can be reduced in size and weight. It becomes possible.

  When the center seat 30 is not a detachable type, the end portions 22 of both armrests 20 may be replaced with a configuration in which the center seat 30 is rotatably supported with respect to the seat back 32 of the center seat 30. That is, the present invention (first invention) includes a case where the armrest 20 is attached to the seat back 12 of both side seats 10 and a case where the armrest 20 is attached to the seat back 32 of the center seat 30. Similarly, the present invention includes the case where there is one armrest 20.
