[Industrial applications]

 The present invention relates to an armrest device for a vehicle seat.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, in a vehicle seat, particularly a rear seat, an armrest device that is capable of being stowed and unfolded is provided at a center portion in a width direction of a seatback from the viewpoint of enhancing a relaxed feeling when a passenger is seated. It is widely practiced. This arm rest device is generally constructed by pivotally supporting one end of an armrest so as to be tiltable in the seat longitudinal direction with respect to a mounting bracket provided in a recess formed on the seat back side. The armrest forms a part of the seat back on the back side when the armrest is stored in the recess, and when the armrest extends from the recess to the front of the seat and extends substantially horizontally, It is designed to support the elbow.

By the way, in the armrest device in which the armrest is arranged so that it can be stored and deployed in the recess formed in the seat back, the recess is covered by the armrest when the armrest is stored in the recess. Along with this, the aesthetic appearance is not impaired because the armrest forms a part of the seat back, but when the armrest in which the armrest is deployed in front of the seat is used, the concave portion is opened so that The mounting bracket arranged in the recess is exposed to the outside, which is not preferable in terms of aesthetics.

Under such circumstances, it has been attempted to secure the aesthetic appearance of the seat by covering the mounting bracket portion and blindfolding the mounting bracket portion when the armrest is deployed.

For example, in Japanese Utility Model Publication No. 54-9792 (first conventional example), one end of a strip-shaped skin material serving as a blinding material is sewn to the base end portion of an armrest, while the other end is recessed. It is disclosed that the resin plate is pulled out to the side and fixed to the resin plate, and the resin plate is inserted and fixed to a bracket provided on the bottom side of the recess, so that the mounting bracket portion is covered with the skin material.

On the other hand, in Japanese Unexamined Patent Publication No. 61-139529 (second conventional example), the other end of a skin material whose one end is sewn to the base end of an armrest is taken out to the mounting bracket side. Pull this from above the mounting bracket to the back side of the fastening and fixing part and sandwich it between the fastening and fixing part of the mounting bracket and the fixing part on the seat back side and tighten together with them. It is disclosed that the mounting bracket is fixed and covered with the skin material.

[0007]

[Problems to be solved by the device]

 However, in each of the above-mentioned conventional examples, while the original purpose of ensuring the aesthetic appearance of the seat by covering the mounting bracket portion when the armrest is in use can be achieved, the assembly of the armrest device at the time of seat production is achieved. There is room for improvement in terms of workability or reliability in use. That is, in the first conventional example, the work of fixing the blindfold skin material is a separate process from the work of assembling the armrest and the mounting bracket and the work of fixing these to the seat back side. After assembling the mounting bracket and the mounting bracket, and then integrally assembling them on the seat back side, the other end of the above-mentioned skin material must be pulled out and fixed to the seat back side, which requires a lot of man-hours and cost. Is disadvantageous to In addition, since the work of fixing the other end of the skin material is performed after the assembly of the armrest device is completed, the work space is restricted by the existence of the armrest device, which makes the work difficult to perform and the workability is deteriorated accordingly. Can also be considered.

On the other hand, in the second conventional example, since the other end of the skin material is interposed between the fastening fixing surface of the mounting bracket and the fixing portion on the seat back side, the mounting rigidity of the mounting bracket is reduced. It is possible that the bolt tightening force will gradually decrease due to the "fatigue" of the skin material during long-term use and the armrest device will rattle during long-term use. It is not preferable in terms of points.

Therefore, the present invention has been made for an armrest device for a vehicle seat provided with a skin material for blindfolds so as to make the assembling workability good and maintain a high level of reliability in use. Is.

[0010]

[Means for Solving the Problems]

 In the present invention, as a concrete means for solving such a problem, a mounting bracket which is fastened and fixed to a fixing member provided in a recess formed in the seat back, and one end of which is attached to the front and rear of the seat with respect to the mounting bracket. And an armrest that is pivotally supported in the first direction and is stored in the recess to form a part of the seat back in the first state, and is unfolded from the recess to the front of the seat in the second state. In an armrest device for a vehicle seat including the above, one end of a substantially strip-shaped extended skin material having a width dimension capable of covering the mounting bracket is sewn onto the base end portion of the armrest, and the extension is performed. A resin plate material having appropriate flexibility is fixed to the other end of the extended skin material in the width direction of the extended skin material, and further at a substantially central portion in the width direction of the other end of the extended skin material. And close to the above resin plate A slit that extends in the width direction of the extended skin material is formed at the position where the above-mentioned mounting bracket is provided, while the above-mentioned mounting bracket has a fastening fixing portion where the portion orthogonal to the tilting surface of the armrest is abutted and fixed to the above-mentioned fixing member. At the same time, the fastening fixing portion extends upward or downward at a position approximately at the center in the width direction and with a predetermined gap secured between the fastening fixing portion. The first pawl member and the first pawl member sandwiched in the widthwise direction are positioned on both sides of the first pawl member, and extend in the direction opposite to the first pawl member in a state where a predetermined gap is secured between the first pawl member and the fastening and fixing portion. And a pair of left and right second claw members that project, and the other end of the extended skin material is provided between the fastening fixing portion and the first claw member and the pair of left and right second claw members. It is configured such that the first claw member can be fitted and held together with the resin plate material in a state of being inserted therethrough. It is characterized by a door.

[0011]

With this configuration, in the present invention, when the armrest device is assembled to the recess side of the seat back, first, the mounting bracket and the armrest, which are in a single item state, are assembled to form an assembly. In this state, take out the other end of the extended skin material, one end of which is sewn to the base end side of the armrest, to the mounting bracket side, and the other end together with the resin plate material fixed here. While appropriately flexibly deforming, fit and hold between the fastening fixing portion of the mounting bracket and the first claw member and the pair of left and right second claw members formed on the fastening fixing part To do. In this case, the slit formed in the other end of the extended skin material is inserted into the first claw member to position the extended skin material and the mounting bracket in the width direction.

After that, the armrest device assembled by the armrest and the mounting bracket and assembled with the extended skin material is integrally moved as it is to the recess side of the seatback, and the mounting bracket is moved to the seatback side. The work of assembling the armrest device is completed by fastening and fixing the armrest device. In this case, since the other end of the extended skin material to which the resin plate material is attached is fitted and held between the fastening / fixing portion of the mounting bracket and each claw member, the presence of the extended skin material. Regardless of this, the fastening fixing portion of the mounting bracket and the fixing member on the seat back side are directly abutted and fastened.

In the armrest device assembled on the seat back side in this way, the mounting bracket is covered by the extended skin material in the use state in which the armrest is deployed to the front of the seat. The seat is not exposed to the outside, and the aesthetic appearance of the seat is maintained when the armrest is used.

[0014]

[Effect of device]

 Therefore, according to the armrest device for a vehicle seat of the present invention, the following effects can be obtained. Since the work of fixing the other end of the extended skin material can be performed at the same time as the work of assembling the armrest and the mounting bracket, and independently of the seat back side, the work can be performed under a sufficient work space. It can be performed easily, surely and quickly, and the work reliability and good workability are secured.

The fixing of the other end of the extended skin material is achieved by an extremely easy work of fitting the other end together with the resin plate material provided here to the respective claw members on the mounting bracket side. Since the work can be performed away from the seat back under a sufficient working space, the work of fixing the extended skin material can be further simplified and the workability can be further improved.

When fixing the other end of the extended skin material, the slit provided here is inserted into the first claw member on the side of the mounting bracket to position the extended skin material and the mounting bracket in the width direction. Done. For this reason, once the first claw member is inserted through the slit, it is possible to fix the extended skin material without worrying about the relative position between the mounting bracket and the extended skin material. Various work is possible. In addition, the accurate positioning surely avoids the occurrence of inconveniences such as the displacement of the extended skin material and the mounting bracket in the width direction and the exposure of the mounting bracket from the extended skin material. Ensuring the aesthetic appearance of the seat, which is the original function of the skin material, will be more reliable.

Since the mounting bracket is assembled to the seat back side in a state where the armrest, the mounting bracket, and the extended skin material are integrated, care should be taken for the skin material whose other end is free as in the conventional case. However, compared with the case where the mounting bracket is fixed to the seat back side and the other end of the above-mentioned skin material is fixed after this fixing work, the armrest and the like are easier to handle, and the armrest device is attached to the seat back side more easily. The workability in the fixing work is improved.

In the state where the mounting bracket is fastened and fixed to the fixing member on the seat back side, the end portion of the extended skin material does not intervene between them, so that the mounting rigidity is high and the rigidity is long-term use. It is possible to continue to use the armrest device in good condition for a long time without any deterioration, and the reliability of use of the armrest device can be improved.

【Example】

 Hereinafter, the armrest device for a vehicle seat according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a vehicle rear seat 1 provided with an armrest device 4 according to an embodiment of the present invention. Has been done. The seat 1 is composed of a seat cushion 2 and a seat back 3 which is vertically arranged at a rear end portion of the seat cushion 2 so as to be inclined rearward. Further, the seat back 3 is a left-right two-part type including a first seat back member 31 and a second seat back member 32, and these seat back members 31, 32 are tilted forward selectively or simultaneously. You can do it. Of the seat back members 31 and 32, the first seat back member 31 is wider than the second seat back member 32, and the end portion near the center thereof corresponds to the center portion in the width direction of the seat back 3. A substantially rectangular recess 33 is formed in the seat back front surface and extends in the vertical direction. The armrest device 4, which will be described later, is stored in the recess 33 when the armrest device 4 is in a stored state (corresponding to the “first state” in the scope of the utility model registration request and is in a state shown by a solid line in FIG. 1) and in use. It is arranged so that the posture can be arbitrarily set between it and the state (which corresponds to the “second state” in the scope of claims for utility model registration, which is the state shown by the chain line in FIG. 1).

As shown in FIGS. 2 to 4, the armrest device 4 includes an armrest 5 and a mounting bracket 6 for mounting the armrest 5 on the seatback 3 side.

The armrest 5 has a substantially rectangular block shape, and is constructed by covering the outside of a pad material 11 arranged so as to cover a frame (not shown) with a skin material 12. ing. The base end portion 5a of the armrest 5 is formed with bolt receiving holes 18, 18 which serve as a mounting portion for a mounting bracket 6 described later.

On the upper surface 5b side of the base end portion 5a of the armrest 5, a strip-shaped extended skin material 14 made of the same material as the skin material 12 of the armrest 5 and having substantially the same width dimension as the armrest 5 is provided. One end 14a is sewn so that the extended skin material 14 can be extended rearward from the base end 5a of the armrest 5. Further, the extended skin material 14 has the other end 14b as a free end, and a band-shaped resin plate material 15 having appropriate flexibility is sewn to the other end 14b in the width direction of the other end 14b. It is fixed by sticking. Further, a slit of a predetermined length extending along the resin plate material 15 is provided at a position in the center in the width direction of the other end 14b of the extended skin material 14 to which the resin plate material 15 is attached and close to the resin plate material 15. 16 are formed.

On the other hand, the mounting bracket 6 is formed integrally by bending a plate material into a “U” shape, and the portion located at the center in the longitudinal direction is the fastening / fixing portion 21. The left and right sides of the fastening / fixing portion 21 are defined as arm portions 22, 22 that are continuous with each other in a bent state. Bolt insertion holes 23, 23 are formed at the tips of the arm portions 22, 22 of the mounting bracket 6, respectively.

Further, the fastening / fixing portion 21 has a first surface portion 21a located in the lower half portion, and a second surface portion located in the upper half portion and offset to the arm portion 22 side with respect to the first surface portion 21a. The surface portion 21b is formed in a stepped surface shape. Then, in a substantially central portion in the width direction of the fastening / fixing portion 21, with the first surface portion 21a side as a base end, the same surface as the first surface portion 21a is cut and raised from the second surface portion 21b side. A first pawl member 26 extending upward is formed. Further, at both left and right positions sandwiching the first claw member 26 in the width direction, the first claw member is cut and raised from the first surface 21a side with the second surface 21b side as a base end and in the plate thickness direction. A pair of left and right second claw members 27, 27 is formed so as to be bent at the same position as 26 and extend downward.

Therefore, although the extending directions of the first claw member 26 and the second claw members 27, 27 are opposite to each other, the first claw member 26 and the second claw members 27, 27 are located at substantially the same height from the second surface portion 21b. However, a predetermined size is provided between each of the claw members 26, 27, 27 and the second surface portion 21b (specifically, the thickness of a portion where the extended skin material 14 and the resin plate material 15 are combined). A gap having a size such that it can be fitted in the depth direction is formed. Further, a pair of left and right fixing bolts 25, 25 are vertically arranged on the first surface portion 21a of the fastening and fixing portion 21.

The armrest 5 and the mounting bracket 6 thus configured are assembled by the following procedure to form the armrest device 4 as shown in FIG. The procedure for assembling the armrest device 4 will be described. First, as shown in FIG. 3, the base end portion 5a side of the armrest 5 is fitted between the arm portions 22, 22 of the mounting bracket 6 in the single product state. Then, the pivot support bolts 24, 24 inserted into the bolt insertion holes 23, 23 of the arm portions 22, 22 are screwed into the bolt receiving holes 18, 18 of the armrest 5 to integrally integrate the bolts. Connect to. In this connected state, the armrest 5 and the mounting bracket 6 are rotatable relative to each other about the pivot bolts 24, 24.

Next, the other end 14b side of the extended skin material 14 is taken out to the fastening / fixing portion 21 side of the mounting bracket 6, and the other end 14b is folded in half at the resin plate material 15 portion. In this state, first, the first claw member 26 is inserted into the slit 16 on the side of the extended skin material 14, and the mounting bracket 6 and the extended skin material 14 are positioned in the width direction. Further, while appropriately bending and deforming the resin plate member 15, the first claw member 26 and the pair of second claw members 27 are passed over from the front surface side to the rear surface side, respectively, and the second surface portion. 21b is fitted into the gap (this fitting completion state is the state shown in FIG. 4).

When the other end 14b of the extended skin material 14 is fitted and held together with the resin plate material 15 on each of the claw members 26, 27, 27 on the side of the mounting bracket 6, the movement in the width direction is as described above. Since the first claw member 26 is inserted into the slit 16, the first claw member 26 and the pair of second claw members 27 holding the resin plate material 15 and the like move in the opposite claw direction in the vertical movement. As a result, the other end 14b is surely fixed and held on the side of the mounting bracket 6 because it is regulated.

As described above, in the armrest device 4 of this embodiment, the resin plate material 15 is appropriately deformed with the slit 16 on the extended skin material 14 side being inserted into the first claw member 26 on the mounting bracket 6 side. The other end 14b of the extended skin material 14 can be fixed to the mounting bracket 6 side by a very simple work of engaging with the claw members 26, 27, 27 while doing so. The other end 14b of the skin material 14 can be fixed to the armrest device 4 in a single product state before being assembled to the seat back 3 side, and without being restricted by the work space. Therefore, the fixing work of the extended skin material 14 can be performed reliably and easily. For example, as in the case where the other end 14b of the extended skin material 14 is fixed after the armrest device 4 is assembled to the seatback 3 side. The workability is much better than that of work space constraints.

On the other hand, the armrest device 4 assembled as described above is finally tightened and fixed in the recess 33 of the seat back 3. That is, as shown in FIG. 4, the armrest device 4 integrated with the extended skin material 14 is moved directly to the recess 33 side of the seatback 3 as shown in FIG. 21 is abutted against a fixing member 42 provided on the bottom of the recess 33 near the lower end, and nuts are attached to the fixing bolts 2525 to fasten and fix them. In FIG. 2, reference numeral 41 is a seat back frame, and the fixing member 42 is fixed to the seat back frame 41. Further, reference numeral 43 is a back surface member 43, and the back surface member 43 constitutes the bottom surface of the recess 33.

By the way, when fastening and fixing the armrest device 4 to the concave portion 33 side, since the other end 14b of the extended skin material 14 has already been fixed to the mounting bracket 6 side, the fixing of the mounting bracket 6 It is possible to perform the abutting operation on the member 42 without worrying about the other end 14b of the extended skin material 14, and for example, the other end 14b of the extended skin material 14 is freed as in the conventional case. Therefore, compared to the case where it is necessary to fix the mounting bracket 6 while removing it, the work is easy and quick, and high workability is realized.

When the mounting bracket 6 is fastened and fixed to the fixing member 42, the first surface portion 21 a of the fastening and fixing portion 21 of the mounting bracket 6 directly abuts the fixing member 42. Therefore, for example, it is difficult to secure the assembling rigidity as in the case where the extended skin material 14 is interposed between them as in the conventional case, or the “extent” of the extended skin material 14 is caused by long-term use. Because of this, the fastening force is reduced and the armrest device 4 does not rattle or the like, which is advantageous in terms of its mounting rigidity or reliability in use.

As described above, the armrest device 4 assembled to the seatback 3 side is rotated toward the seatback 3 side about the pivot bolt 24 as shown by a solid line in FIGS. 1 and 2 when the armrest is not used. It is moved and stored in the recess 33. Then, in this stored state, the back surface 5c of the armrest 5 is exposed to the seat front surface side and constitutes a part of the seat back 3. Further, in this case, since the recess 33 is closed by the armrest 5, there is no problem in terms of aesthetics.

On the other hand, when the armrest 5 is used, the armrest 5 in the retracted state is pulled out to the front and is extended to the front of the seat as shown by the chain line in FIGS. The position of the armrest 5 in the turning direction is restricted by a position restriction mechanism (not shown). In this in-use state, the recess 33 is exposed on the front side of the seat, but the mounting bracket 6 located at the lower end of the recess 33 straddles between the mounting bracket 6 and the base end 5a of the armrest 5. It is not exposed to the outside because it is covered by the extended skin material 14 thus arranged, and as a result, good aesthetic appearance is ensured.
