  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

  First, the configuration of the vehicle seat 1 according to the first embodiment will be described with reference to FIGS. The vehicle seat 1 of the present embodiment is configured as a passenger seat of an automobile as shown in FIGS. 1 to 2, and includes a seat back 2 that serves as a backrest for a seated occupant and a seat cushion 3 that serves as a seating portion. And comprising. The seat back 2 has a structure in which a headrest 2A for supporting the head of a seated occupant is integrally formed on the upper portion thereof.

  On the back portion 2B of the seat back 2, a detachable holding tool 10 (attachment) that allows an occupant of the rear seat to attach and hold the mobile device P is disposed. Specifically, the holder 10 is configured to be attached to a main body portion 21 of a movable position adjusting mechanism 20 connected to the back portion 2B of the seat back 2. Here, the mobile device P in the present embodiment is a so-called tablet computer, which has a flat outer shape, and has a configuration in which a display / input unit such as a touch panel is provided on the monitor unit Pa on the surface. Yes. The mobile device P has a narrow groove-like engagement groove Pb that is cut into a slit shape over the entire outer periphery. When the mobile device P is slid so as to be inserted into the holder 10 from above, the engagement grooves Pb formed on both sides of the mobile device P are formed on the engagement claws 11A formed on the holder 10. It is engaged and attached to the holder 10 so as to be held.

  Here, as shown in FIG. 2, the holder 10 is formed with a guide wall 11 projecting in a standing wall shape on the rear side on each of the left and right and lower peripheral portions of the main plate formed in a flat plate shape. It becomes the composition. The guide wall 11 is configured to guide the outer peripheral portion of the mobile device P by being applied to the left and right outer peripheral surfaces of the mobile device P inserted into the holder 10. On the inner peripheral surface of the guide wall 11, the above-described engaging claws 11 </ b> A are formed so as to project in a streak shape so as to cross the inner peripheral surface of each standing wall. The engaging claws 11A are inserted into the engaging grooves Pb on both the left and right sides of the mobile device P by sliding the mobile device P from the upper side with respect to the holder 10 and inserting it. The mobile device P is configured to guide the insertion of the mobile device P by sliding into the holder 10 along the protruding shape, and to hold the mobile device P after the insertion so as not to drop out of the holder 10.

  Next, the configuration of the position adjustment mechanism 20 will be described. The position adjusting mechanism 20 is normally provided so as to be housed in a recess 2C formed in the back portion 2B of the seat back 2 (see FIG. 2). The position adjusting mechanism 20 is configured to fold down the tennis racket frame-type main body 21 to which the holder 10 described above is attached to the rear side of the seat back 2 when desired (see FIG. 10) or attach it to the main body 21. The vertical angle of the holder 10 is changed (see FIG. 11), the main body portion 21 itself is pulled out from the back portion 2B of the seat back 2 (see FIG. 12), and the length of the main body portion 21 itself is expanded and contracted (FIG. 15). Thus, the arrangement position and the vertical angle of the holder 10 in the front-rear direction and the height direction of the holder 10 can be freely adjusted.

  Specifically, as shown in FIG. 2, the position adjusting mechanism 20 pivots rearward by axially connecting the base portion 21 </ b> C on the lower end side of the main body portion 21 to the back portion 2 </ b> B of the seat back 2 (see FIG. 10). The first hinge part 20A to be moved and the holder 10 described above to be detachably connected to the main body part 21 so as to be swung in the height direction (see FIG. 11). Hinge part 20B, an extension part 20C that allows the intermediate part 21B of the main body part 21 to expand and contract (FIG. 15), and the main body part 21 are slidably connected to the back part 2B of the seat back 2 and slid rearward. (Refer to FIG. 12). Hereinafter, the configuration of each unit will be described in detail in order.

  As shown in FIG. 5, the first hinge portion 20 </ b> A has a hinge pin on a slider 23, which will be described later, arranged so that the base portion 21 </ b> C of the main body portion 21 is slidable back and forth in the recess 2 </ b> C of the back portion 2 </ b> B of the seat back 2. It is configured to be axially coupled via 21C1 so as to be rotatable in the front-rear direction. Between the slider 23 axially connected via the hinge pin 21C1 and the base portion 21C of the main body portion 21, a bushing that applies an elastic force in the axial direction between them and applies a frictional resistance force during sliding. 21C2 is interposed. Due to the frictional resistance generated by the elastic force of the bush 21C2, the main body 21 is configured such that the rotational position of the seat back 2 relative to the back portion 2B (slider 23) is stopped at an arbitrary rotational position. The rotation is stopped at a position stored in the recess 2C of the back portion 2B of the back 2 and various backward tilted positions rotated and developed rearward from the storage position.

  Next, as shown in FIG. 3, the second hinge portion 20B is connected to the round bar portion 21A1 interposed in the joint portion at the upper end of the annular loop portion 21A that forms the upper portion of the main body portion 21. The beak-shaped fitting portion 12 formed at the lower back of the holder 10 is fitted from the rear side so that it can be pivotally connected to the shaft. The round bar portion 21A1 has a round bar shape smaller in diameter than the loop portion 21A. When the loop portion 21A is housed in the concave portion 2C that is similar to the loop portion 21A, A gap 2D in which the beak-shaped fitting portion 12 can be fitted is formed between them.

  On the other hand, the fitting portion 12 has a beak shape that protrudes from the lower rear portion of the holder 10 toward the back side (side to be attached to the main body portion 21), and the round bar portion is formed in the beak-shaped receiving port 12A. 21 </ b> A <b> 1 is received in the radial direction, and is configured to be pivotally coupled to the round bar portion 21 </ b> A <b> 1 so as to be rotatable. Specifically, the receiving port 12A has a beak shape in which an inner peripheral surface is curved in a C shape, and a leaf spring 12B having a C shape on the inner peripheral surface has an opening. Similarly, it is configured to be fitted. A rotating screw type adjustment knob 12C is attached to the lower portion of the fitting portion 12 by screwing the screw 12C1. The screw 12C1 is screwed and inserted from below the lower beak of the fitting portion 12, and the upper end surface of the insertion destination is in contact with the lower surface of the C-shaped leaf spring 12B.

  The screw 12C1 is operated by an occupant of the rear side seat turning the adjustment knob 12C with a finger, so that the screwing position is advanced or returned, and the leaf spring 12B is pushed in from the lower side to be C-shaped. The operation is performed to narrow the shape or to widen the C shape by softening the push-in. Therefore, by adjusting the adjustment knob 12C, the beak shape of the fitting portion 12 described above is fitted into the round bar portion 21A1 from the rear side in a state where the C-shape of the leaf spring 12B is expanded, and the receiving port 12A After the round bar portion 21A1 is received, the adjustment knob 12C is operated to narrow the C-shape of the leaf spring 12B so that the fitting portion 12 is rounded by the round bar portion 21A1. It can be attached in a state of being crimped to the portion 21A1 (see FIG. 4).

  In this crimped state (see FIG. 4), the inner peripheral surface of the C-shaped leaf spring 12B is pressed against the round bar portion 21A1 from the upper and lower sides. Therefore, if this pressing force is strengthened by operating the adjustment knob 12C, the fitting portion 12 (holding tool 10) is held in a state in which it is prevented from rotating by applying a high sliding frictional resistance force to the round bar portion 21A1. Can do. Further, if the pressing force is weakened, the fitting portion 12 (holding tool 10) can be brought into a weak fitting state in which the fitting portion 12 (holding tool 10) can be swung in the height direction around the round bar portion 21A1. Further, by operating the adjustment knob 12C and setting the pressing force to a moderately strong state, while holding the fitting portion 12 (holding tool 10) in a free state, By turning with force, the swing angle of the fitting portion 12 (holding tool 10) can be changed, and the angle of the holding tool 10 can be changed without operating the adjustment knob 12C each time. Adjustment can be made easily.

  Next, as shown in FIG. 7, the expansion / contraction part 20C extends the intermediate part 21B between the loop part 21A and the root part 21C of the main body part 21 described above with reference to FIG. It is configured to be changed. Specifically, the intermediate part 21B is divided into an upper part 21B1 and a lower part 21B2, and a bar-like stay 21B1a coupled to the upper part 21B1 is inserted into the lower part 21B2. The upper part 21B1 is extended (see FIG. 8) or contracted with respect to the lower part 21B2 by changing the insertion amount of the stay 21B1a. Here, in the stay 21B1a, cutout grooves 21B1b cut into a right triangle shape are formed at a plurality of locations in the length direction on the outer peripheral surface. Each of the cutout grooves 21B1b has an upper surface of the cutout as a right-angled surface, and a lower surface of the cutout is a tapered surface inclined.

  On the other hand, a frame plate-like claw plate 21B2b is arranged at the upper end of the lower part 21B2 into which the stay 21B1a is inserted so as to be slidable in the radial direction within the cylinder into which the stay 21B1a is inserted. The claw plate 21B2b is normally in a state where one side of the frame is pressed against the outer peripheral surface of the stay 21B1a by the urging force of the compression spring 21B2c provided between the claw plate 21B2b and the lower part 21B2. As a result, the claw plate 21B2b is inserted into the notch groove 21B1b by urging when the stay 21B1a is inserted into the notch groove 21B1b so that the stay 21B1a enters the stay 21B1a. Is held in a state in which movement in the insertion direction is restricted.

  The restriction state of the insertion movement of the stay 21B1a by the claw plate 21B2b is released by an operation in which a passenger in the rear seat pushes the push button 21B2a provided integrally at the end portion of the claw plate 21B2b on the seat rear side. The Specifically, when the push button 21B2a is pushed, the claw plate 21B2b is pushed and operated against the urging force of the compression spring 21B2c, and the frame is engaged in the notch groove 21B1b of the stay 21B1a. Is removed from the notch groove 21B1b, and the restriction state is released. As a result, the stay 21B1a is allowed to move in the insertion direction, and the stay 21B1a moved in the extending direction as shown in FIG. 8 is inserted into the lower part 21B2 to adjust the length of the main body 21. It becomes possible to move.

  When the stay 21B1a is moved in the extending direction, the above-described pressing operation of the push button 21B2a is not necessary. That is, since the shape of each notch groove 21B1b cut into the stay 21B1a described above is a tapered surface with the lower surface of the notch inclined, when the stay 21B1a is moved in the extending direction, the claw plate 21B2b This is because the above-described locking function does not work because the lens moves so as to slide on the tapered surface. Therefore, when the intermediate portion 21B is extended to increase the length of the main body portion 21, the length of the main body portion 21 can be easily adjusted without requiring the operation of the push button 21B2a.

  Next, as shown in FIG. 5, the slide connecting portion 20 </ b> D includes a slider 23 in which the main body portion 21 is hinge-connected to the base 22 that is coupled and fixed in the recess 2 </ b> C of the seat back 2. It is the structure connected so that it could slide in the front-back direction. Specifically, the slider 23 has a slide position (see FIG. 5) housed in the recess 2C of the seat back 2 by the base 22, and a slide position (see FIG. 5) that slides and protrudes to the rear side of the seat back 2. It is guided so that it can slide in the front-back direction.

  By adjusting the slide position of the slider 23, the front-rear position of the main body 21 with respect to the seat back 2 is adjusted. Here, the slider 23 is formed with notched grooves 23A cut into a right triangle shape at a plurality of locations on the outer peripheral surface in the sliding direction. Each of the cutout grooves 23A has a taper surface in which the rear side surface (sheet front side surface) of the cutout is a right angle surface and the front side surface (sheet rear side surface) of the cutout is inclined.

  On the other hand, the base plate 22 that guides the slider 23 is in a state in which a frame-plate-like claw plate 22B is slide-guided so that the slider 23 can slide in a direction perpendicular to the sliding direction of the slider 23. Is provided. The claw plate 22 </ b> B is normally in a state where one side of the frame is pressed against the outer peripheral surface of the slider 23 by the urging force of the leaf spring 22 </ b> A coupled to the base 22. As a result, the claw plate 22B is slid into the notch groove 23A when the slide position of the slider 23 coincides with any one of the notch grooves 23A. The rearward movement is restricted and held.

  The state of restriction of the backward movement of the slider 23 by the claw plate 22B is released by an operation in which the occupant of the rear seat pushes the push button 23B connected to the base 22 so as to be able to be pushed. Specifically, the push button 23B is connected to the base 22 via a compression spring 23C, and is normally exposed to the back portion 2B of the seat back 2 by the urging force of the compression spring 23C. As a state of being pushed out, the stopper pin 22C coupled to the base 22 is held in a locked state. When the push button 23B is operated so as to be pushed into the back portion 2B of the seat back 2 against the urging force of the compression spring 23C, a tapered surface 23B1 formed at a midpoint of the trunk portion is formed. The claw plate 22B is pushed out in the direction against the urging force of the plate spring 22A, and is removed from the notch groove 23A of the slider 23, thereby releasing the above-described restricted state. By releasing the restriction, the slider 23 is allowed to move backward. As shown in FIG. 6, the occupant of the rear seat holds the main body 21 and pulls the slider 23 backward. 23 will be in the state which can adjust a slide position to back side.

  Note that when the slider 23 is pushed back into the seat back 2, the above-described pressing operation of the push button 23B is not necessary. That is, the shape of each notch groove 23A cut into the slider 23 described above is a tapered surface where the front side surface (sheet rear side surface) of the notch is inclined, so that the slider 23 is moved forward. This is because the above-described locking function does not work because the claw plate 22B moves so as to slide on the tapered surface. Therefore, when the slider 23 pulled out to the rear side is returned to the front side, the front / rear position of the main body 21 can be easily adjusted without requiring the operation of the push button 23B.

  As shown in FIGS. 9 to 18, the position adjustment mechanism 20 configured as described above includes the first hinge part 20 </ b> A, the second hinge part 20 </ b> B, the expansion / contraction part 20 </ b> C, and the slide connection part 20 </ b> D described above. By appropriately operating, the arrangement position and the vertical angle of the mobile device P attached to the holder 10 attached to the main body 21 can be adjusted in various ways. Hereinafter, a method for adjusting the arrangement position and the angular position of the holder 10 (mobile device P) by the above-described position adjustment mechanism 20 will be specifically described as a usage method of the present embodiment.

  As shown in FIG. 9, the position adjustment mechanism 20 described above is configured so that the fitting portion 12 of the holder 10 is connected to the second portion of the main body portion 21 in a state where the main body portion 21 is housed in the recess 2 </ b> C of the back portion 2 </ b> B of the seat back 2. The two hinge portions 20B can be fitted and connected to the shaft. Therefore, the holder 10 can be attached to or detached from the main body 21 without pulling out the main body 21 from the inside of the recess 2C of the back portion 2B of the seat back 2, and this detaching operation can be easily performed. Further, the mobile device P is attached to the back portion 2B of the seat back 2 by attaching the holder 10 to the main body portion 21 and attaching the mobile device P to the holder 10 while the main body portion 21 is housed in the recess 2C. The occupant in the rear seat can see the monitor of the mobile device P in a state of being attached along the wall.

  When it is desired to use the mobile device P close to the passenger in the rear seat, first, the main body portion 21 is tilted back around the first hinge portion 20A (see FIG. 10), and then the holder 10 May be rotated upward around the second hinge portion 20B (see FIG. 11). Accordingly, the mobile device P can be effectively and easily brought closer to the passenger in the rear seat, and the monitor unit Pa can be adjusted so as to be directed toward the passenger. By adjusting the monitor unit Pa so as to face upward, the input operation of the touch panel can be easily performed. The tilting amount of the main body 21 and the swinging amount of the holder 10 can be kept at freely adjusted positions.

  In addition to the above method, the mobile device P can be brought closer to the passenger in the rear seat as follows. That is, from the initial state shown in FIG. 9 described above, by pulling the main body portion 21 to the rear side using the configuration of the slide connecting portion 20D, as shown in FIG. 12, the holder 10 (mobile device P) Without changing the angle direction and the height position, the holder 10 (mobile device P) can be brought closer to the passenger in the rear seat as it is. Further, from this state, as in the method described above, the main body portion 21 is tilted rearward around the first hinge portion 20A (see FIG. 13), and the holder 10 is moved around the second hinge portion 20B. (See FIG. 14), the holder 10 (mobile device P) can be further brought closer to the passenger in the rear seat. The pull-in amount of the main body 21 to the rear side can also be kept at a freely adjusted position.

  In addition, as shown in FIG. 15, after the main body portion 21 is tilted backward, the length of the main body portion 21 is adjusted using the configuration of the extendable portion 20 </ b> C, so that the mobile device P can be adjusted. The height of the arrangement position can be adjusted more effectively and simply without changing the angle direction (see FIG. 16). The length of the main body 21 can be adjusted at a freely adjusted position. In addition, if the length of the main body 21 is adjusted using the configuration of the telescopic portion 20C from the state in which the main body 21 shown in FIG. 12 is retracted to the rear side, as shown in FIG. The height of the arrangement position can be adjusted more effectively and simply without changing the angular orientation of the mobile device P at the position pulled back.

  Further, when it is desired to move the mobile device P away from the front side without changing its angular orientation and height position, as shown in FIG. 18, the main body portion 21 is seated back using the configuration of the slide connecting portion 20D. It may be operated so as to push it into 2. At this time, in the case where the main body portion 21 is extended by the telescopic portion 20C, when the forward sliding operation is performed to the limit position, the main body portion 21 hits the back portion 2B of the seat back 2 and slightly later Although it tilts, the mobile device P can be used in a state of being moved to a high arrangement position in a state close to wall mounting by adjusting the holder 10 upward around the second hinge portion 20B.

  The operation example of the position adjusting mechanism 20 described above is merely an example, and each operation of the first hinge portion 20A, the second hinge portion 20B, the telescopic portion 20C, and the slide connecting portion 20D of the main body portion 21 is described. By this combination, the mobile device P can be brought closer to the occupant of the rear seat in various ways. For example, when the mobile device P is used by an occupant with a short height such as a child, the configuration of the second hinge portion 20B may be used to adjust the monitor portion Pa to face obliquely downward. it can.

  As described above, according to the configuration of the vehicle seat 1 of the present embodiment, the position adjusting mechanism 20 can adjust the arrangement position of the holder 10 (front-rear position, height position, and vertical angle orientation). Thus, even when the seat position of the vehicle seat 1 (front and rear slide position and backrest angle of the seat back 2) is changed, the convenience of the holder 10 can be kept good. Further, since the position adjusting mechanism 20 is provided with the slide connecting portion 20D, when the passenger in the rear seat holds the mobile device P on the holder 10 and uses it for browsing the screen, the main body portion 21 is used. By adjusting the slide position, it is possible to easily perform adjustment to change only the front-rear position without changing the height position of the mobile device P. Even when the main body 21 is housed in the recess 2C of the back portion 2B of the seat back 2, the holder 10 is configured to be detachable from the main body 21 by setting the gap 2D as described above. The tool 10 can have a highly convenient configuration.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, in the above-described embodiment, as a configuration of the second hinge portion 20B that detachably connects the holder 10 to the main body portion 21, the round bar in which the fitting portion 12 set in the holder 10 is set in the main body portion 21. Although the configuration in which the shaft 21 is detachably connected to the portion 21A1 is illustrated, a configuration in which a fitting portion is set in the main body portion and a round bar portion is set in the holder may be used. In addition, the second hinge part is not limited to the shaft connection structure formed by the fitting part and the round bar part as described above, and a mounting part having a hinge structure is set on one of the main body part or the holder, and the other Further, a configuration may be adopted in which the mounting portion and the mountable mounting portion are set.

  Further, in the above embodiment, as shown in FIGS. 5 to 6, the slide connecting portion 20D is configured to require the operation of the push button 23B when the slider 23 is pulled out to the rear side, and to be pushed when pushed forward. Although the configuration that does not require the operation of the button 23B is exemplified, the configuration may be reversed. That is, the push button is not required to be operated when the slider is pulled backward, and the push button is required to be pressed when the slider is pushed forward. Thereby, when it is desired to pull out the main body portion backward, the operation can be easily performed. In addition, without setting a push button, a bush is set between the slider and the base (seat back) so that the slider can be locked at an arbitrary slide position by applying a resistance force caused by sliding friction. It may be.

  Similarly, the structure of the first hinge part of the main body part is configured to prevent rotation by setting a locking mechanism such as a ratchet meshing structure instead of the structure in which the rotation is stopped by the frictional resistance force by the bush. Also good.
