However, the present invention is not construed as being limited to the description of the embodiments below. Those skilled in the art will readily understand that the specific configuration can be changed without departing from the spirit or the spirit of the present invention.

  In the structures of the invention described below, the same portions or portions having similar functions are denoted by the same reference numerals in different drawings, and description thereof is not repeated.

  The position, size, shape, range, and the like of each component illustrated in the drawings and the like may not represent the actual position, size, shape, range, or the like in order to facilitate understanding of the invention. For this reason, the present invention is not necessarily limited to the position, size, shape, range, and the like disclosed in the drawings and the like.

Below, the example which applied this invention to the seat for three seats of the rear seat of a passenger car is demonstrated.
FIG. 1 is a perspective view of a three-seat seat 100 in the rear seat of a passenger car equipped with seats 110, 120, and 130, and shows a state in which an armrest 133 is stored in a seat back 132 of a central seat 130. The seats 110, 120, and 130 include seat cushions 111, 121, and 131 on which a passenger sits and seat backs 112, 122, and 132 that support the back of the seated passenger.

  A belt 134 is attached to the armrest 133 for hooking a hand when the armrest 133 is tilted forward.

  FIG. 2 shows a state in which the armrest 133 is tilted forward. In this state, the passenger seated on the seats 110 and 120 can put an elbow on the armrest 133 or place an accessory or a magazine on the armrest 133.

  Thus, the external appearance of the armrest 133 that can be tilted forward or stored in the seat back 132 is shown in FIG. The armrest 133 is provided with a pair of stopper pins 1332 on the left and right for restricting the rotation range of the shaft 1331 and the armrest 133 as the center of rotation. Further, the lower portion 1330 of the armrest 133 is formed so that the width dimension W3 is narrower than the width dimension of the upper portion for assembly to be described later.

  On the other hand, the external appearance of the seat back 132 storing the armrest 133 is shown in FIG. The seat back 132 is formed with an armrest storage portion 135 for storing the armrest 133. Supporting plates (seat back plates) 136 for supporting the shaft 1331 and the stopper pin 1332 of the armrest 133 are respectively installed on a pair of opposing side surfaces 1351 of the armrest storage unit 135. The support plate 136 is also attached to the side surface of the armrest storage unit 135 that faces the side surface 1351, and a pair of support plates 136 are provided on the left and right side surfaces of the armrest storage unit 135.

  FIG. 5 shows a front view of the support plate 136. The support plate 136 is formed with a shaft hole 1361 for inserting and supporting the shaft 1331 and a guide hole 1362 for defining an operation range of the stopper pin 1332. The support plate 136 is fixed to a frame of the seat back 132 (not shown) with a fastening member such as welding or a screw.

  The armrest 133 rotates around the shaft 1331 inserted into the shaft hole 1361 of the support plate 136 fixed to the frame. The range in which the armrest 133 rotates is limited by a guide hole 1362 that guides the stopper pin 1332.

  By incorporating the armrest 133 shown in FIG. 3 into the armrest storage part 135 formed on the seat back 132 as shown in FIG. 4, the state shown in FIGS. 1 and 2 is obtained. The interval W1 between the tip portions of the stopper pins 1332 fixed to the armrest 133 is larger than the interval W2 between the pair of support plates 136 fixed to the left and right side surfaces 1351 of the armrest storage unit 135. Therefore, when the armrest 133 is incorporated into the armrest storage unit 135, first, the shaft 1331 is inserted into the shaft hole 1361 of the support plate 136 on one side with the armrest 133 being inclined, and the stopper pin 1332 is inserted into the guide hole 1362. Is inserted to the end, the armrest 133 is made parallel to the armrest storage part 135, and the shaft 1331 and the stopper pin 1332 on the other side of the armrest 133 are formed in the support plate 136 on the other side. 1361 and the guide hole 1362 are inserted.

  Thus, in order to insert the shaft 1331 and the stopper pin 1332 into the shaft hole 1361 and the guide hole 1362 of the support plate 136 with the armrest 133 inclined, the width dimension W3 of the lower portion 1330 of the armrest 133 is set to the armrest storage portion. The distance W2 between the pair of support plates 136 fixed to the left and right side surfaces 1351 of 135 must be set to be somewhat smaller.

  However, after the shaft 1331 and the stopper pin 1332 are inserted into the pair of support plates 136 of the armrest storage unit 135, a gap is generated in the axial direction of the shaft 1331 by the difference between W2 and W3.

  As a result, the shaft 1331 can be easily moved in the axial direction, and the armrest 133 can be easily detached from the support plate 136. Further, when the armrest 133 is rotated in a state where foreign matter is sandwiched between the armrest storage portion 135 and the armrest 133, the guide hole 1362 and the foreign matter are in the state where the foreign matter is in the guide hole 1362 of the support plate 136. There is a risk of being scratched by being pinched by the stopper pin 1332.

  In order to eliminate the problem of the axial gap of the shaft 1331, in this embodiment, a spacer 140 as shown in FIG. 6A is inserted into the gap between the armrest 133 and the support plate 136. The spacer 140 is formed with a shaft guide part 1401 for inserting the shaft 1331 and a stopper pin guide part 1402 for inserting the stopper pin 1332. The spacer 140 is made of a resin such as acrylonitrile butadiene styrene (ABS), polyethylene, polyacetal, or polypropylene.

  FIG. 6B shows a front view of the spacer 140. In the spacer 140, an opening 1411 is formed between the right protrusion 1405 and the central protrusion 1406, and a shaft guide part 1401 is formed at the back of the opening 1411. Micro projections 1412 and 1413 are formed on a part of the shaft guide portion 1401. With this configuration, the shaft 1331 once entering the shaft guide part 1401 cannot be easily pulled out of the shaft guide part 1401 by the minute protrusions 1412 and 1413, and the spacer shaft guide part 140 is securely attached to the shaft 1331. be able to.

  Further, a stopper pin guide portion 1402 is formed between the central protrusion portion 1406 and the left protrusion portion 1407. Micro protrusions 1414 and 1415 are also formed on the stopper pin guide portion 1402. With this configuration, once the stopper pin 1332 is pushed into the stopper pin guide part 1402, the stopper pin 1332 cannot be easily pulled out of the stopper pin guide part 1402 by the minute protrusions 1414 and 1415, and the stopper pin 1332 is removed from the stopper pin 1332. It can be reliably guided by the pin guide part 1402. Further, in order to facilitate opening of the space between the minute protrusions 1414 and 1415 when the stopper pin 1332 is inserted into the stopper pin guide part 1402, the center protrusion 1406 and the left protrusion 1407 are close to the minute protrusions 1414 and 1415, Cavities 1416 and 1417 are formed.

  A recess 1403 is formed in the vicinity of the side where the shaft guide portion 1401 of the spacer 140 is formed, and the thickness is smaller than that of the peripheral portion.

  When the spacer 140 is attached to the shaft 1331 and the stopper pin 1332, first, the stopper pin 1332 is inserted into a stopper pin guide portion 1402 formed between the central protrusion 1406 and the left protrusion 1407. Next, in this state, the shaft 1331 is pushed into the shaft guide portion 1401 from the opening portion 1411 between the right projection portion 1405 and the central projection portion 1406. Here, the width of the opening 1411 is slightly larger than the diameter of the shaft 1331, but the size of the gap between the minute protrusions 1412 and 1413 provided at the entrance of the shaft guide 1401 is the diameter of the shaft 1331. Is smaller than When the shaft 1331 is pushed into the opening 1411 as it is, the minute protrusions 1412 and 1413 abut against the shaft 1331.

  When the shaft 1331 is further pushed in this state, the portion where the concave portion 1403 formed in the spacer 140 is thinner than the surrounding portion is deformed and the right protruding portion 1405 is opened outward, and the minute protruding portions 1412 and 1413 And the shaft 1331 enters the shaft guide part 1401. Once the shaft 1331 enters the shaft guide part 1401, the right protrusion 1405 returns to its original position, and the shaft 1331 is fixed to the shaft guide part 1401.

  FIG. 7 is a view of the state in which the spacer 140 is attached to the shaft 1331 and the stopper pin 1332 and the armrest 133 is stored in the armrest storage portion 135 of the seat back 132 as viewed from the armrest side. This corresponds to the state as shown in FIG. In this state, most of the guide hole 1362 that guides the stopper pin 1332 formed in the support plate 136 is covered with the right protrusion 1405, the central protrusion 1406, and the left protrusion 1407 of the spacer 140.

  In FIG. 7, the left side is the surface on which the passenger sits. Even if foreign matter enters from the left side of the figure, the vicinity of the upper end portion 13621 of the guide hole 1362 is covered with the spacer 140, so foreign matter cannot enter the guide hole 1362.

  On the other hand, FIG. 8 is a view of the armrest 133 viewed from the armrest side in a state where the armrest 133 is rotated from the armrest storage portion 135 around the shaft 1331 and tilted to the front seat cushion 131 side. This corresponds to the state as shown in FIG. In this state, most of the guide hole 1362 that guides the stopper pin 1332 formed in the support plate 136 is covered with the left protrusion 1407 of the spacer 140.

  In FIG. 8, the upper side is the surface on which the passenger puts his elbow. Even if foreign matter enters from the upper side of the drawing, the vicinity of the upper end portion 13621 of the guide hole 1362 is covered with the central protrusion 1406 of the spacer 140, and therefore foreign matter cannot enter the guide hole 1362 from the upper side of the armrest 133. In addition, when foreign matter enters from below the armrest 133, the vicinity of the lower end portion 13622 of the guide hole 1362 is covered with the left protrusion portion 1407 of the spacer 140, so that the foreign matter is not caught in the guide hole 1362.

  Thus, the spacer 140 covers the guide hole 1362 so that foreign matter cannot enter the guide hole 1362, so that the guide hole 1362 is rotated when the armrest 133 shaft 1331 is rotated. The occurrence of a situation where foreign matter is caught between the stopper pin 1332 and the stopper pin 1332 can be prevented.

  FIG. 9 shows an AA cross section in FIG. The spacer 140 is mounted between the armrest 133 and the support plate 136, and bosses 1404 protruding on both sides of the spacer 140 define the distance between the armrest 133 and the support plate 136. That is, by mounting the spacer 140 between the armrest 133 and the support plate 136, rattling between the armrest 133 and the support plate 136 can be suppressed, and the armrest 133 cannot be moved in the axial direction of the shaft 1331. It cannot be removed.

  As shown in FIG. 9, by attaching the spacer 140 between the armrest 133 and the support plate 136 on one side of the armrest 133, there is no gap between the support plate 136 on the other side of the armrest 133. Can do. As a result, foreign matter is not mixed between the support plate 136 on the other side of the armrest 133 or foreign matter is not caught, and a situation where foreign matter is caught between the guide hole 1362 and the stopper pin 1332 occurs. It cannot be done.

  According to the present embodiment, the gap between the armrest 133 and the support plate 136 is blocked by the spacer 140 so that the armrest 133 cannot be moved in the axial direction of the shaft 1331, and the guide hole 1362 of the support plate 136 can be easily removed. And the function of preventing the foreign matter from being caught between the stopper pins 1332, and both functions can be provided in one part.

  According to the present embodiment, since the protrusions 1405, 1406, and 1407 for preventing foreign matter from being caught (mixed) are integrally provided on the spacer 140 for preventing the armrest 133 from rattling, the guide hole There is no need to provide a separate member for preventing foreign matter from being sandwiched between 1401 and 1402, and assembling becomes easy and the cost can be reduced.

  Although the present embodiment has been described as an example applied to a seat for three passengers in the rear seat of a passenger car, the present invention is not limited to this, and vehicles such as passenger cars, aircrafts, trains, ships, buses, etc. It can be applied to a movable armrest that is attached to a seat.

  In this embodiment, an example in which a spacer 150 having a shape as shown in FIG. 10 is used instead of the spacer 140 described in the first embodiment will be described.
