  First, an overall configuration of a vehicle seat 1 to which a seat switch for a vehicle seat according to the present invention is applied will be described with reference to FIG. The vehicle seat 1 includes a seat cushion 10 that is a seating portion of a seated person, a seat back 20 that is configured to be tiltable with respect to the seat cushion 10 and is a seat back portion of the seated person, and an upper portion of the seat back 20. It is comprised from the headrest 30 which is a support part which is assembled | attached to and supports the back head of a seated person. As an example of the vehicle seat 1, a passenger seat disposed in the vehicle will be described as an example.

  The vehicle seat 1 is provided with four types of electric functions A, B, C, and D. Hereinafter, each of these electric functions A, B, C, and D will be described individually. The electric function A is a function for moving the height position and the front / rear position of the front portion of the seat cushion 10 (hereinafter simply referred to as “tilt up / down front / rear function A”). The electric function B is a function of moving the height position and the front-rear position of the support plate disposed in the lower side portion of the seat back 20 (hereinafter simply referred to as “lumbar support function B”). The electric function C is a function for moving the headrest 30 up and down with respect to the seat back 20 (hereinafter, simply referred to as “headrest lifting function C”). The electric function D is a function of tilting the seat back 20 with respect to the seat cushion 10 (hereinafter simply referred to as “reclining function D”). These electric functions A, B, C, and D are implemented by driving means (not shown) (for example, a motor and a cylinder). These electric functions A, B, C, and D are well-known electric functions, and thus detailed description thereof will be omitted.

  Next, the seat switch assembled to the vehicle seat 1 described above will be described with reference to FIG. The sheet switch includes a base 110, a receiving member 120, a rotating member 130, a slide member 140, a case 150, a stopper 170, a shield member 180, and a knob 190. Each of these members will be described individually below.

  First, the description starts in order from the base 110. The board | substrate 110 is comprised from the panel-shaped member. The base 110 is fixed to the left side of a support base (not shown) that supports the seat cushion 10. At this time, the base 110 is fixed so that the plate thickness direction is the vehicle width direction. Further, the base 110 is formed with an engagement hole 111 penetrating in the thickness direction.

  The receiving member 120 includes a ring-shaped cylindrical portion 121 and a suitable closing plate 122 that closes one end (left end in FIG. 2) of the cylindrical portion 121. Of the inner peripheral surface of the cylindrical part 121, the switch S1 is assembled in the vehicle front direction. Similarly, the switch S2 is assembled in the vehicle rear direction. Similarly to this, a switch S3 is assembled in the upward direction of the vehicle. Similarly to this, a switch S4 is assembled in the vehicle downward direction. Each of the switches S1 to S4 is electrically connected to a control device (all not shown) via cable wiring.

  The rotating member 130 includes a ring-shaped cylindrical portion 131, a suitable closing plate 132 that closes one end (right end in FIG. 2) of the cylindrical portion 131, and a direction opposite to the base 110 from the center of the closing plate 132 (FIG. 2). In FIG. 2, the fitting protrusion 133 protrudes in the right direction. An outer peripheral surface of the cylindrical portion 131 is configured to be slidable with respect to an inner peripheral surface of a cylindrical portion 141 of a slide member 140 described later. In addition, support legs 131a are respectively formed at four edges of the peripheral edge of the other end (left end in FIG. 2) of the cylindrical portion 131 that are equally arranged in the circumferential direction.

  The closing plate 132 is a concave surface whose surface slightly enters the edge of one end of the cylindrical portion 131. A thin plate-like short-circuit piece 134 made of a conductor is assembled to the concave surface. The assembly structure of the short-circuit piece 134 will be described in detail. One end of the short-circuit piece 134 is fixed to the concave surface. Further, the other end of the short-circuit piece 134 is bent and warped toward the opposite side with respect to the concave surface. By assembling in this way, a fixed contact 143 and a common contact 144 described later can be electrically connected via the short-circuit piece 134. A semicircular portion 133b having a semicircular cross section is formed at the tip of the fitting protrusion 133.

  The slide member 140 includes a ring-shaped cylindrical portion 141 and a suitable closing plate 142 that closes one end (right end in FIG. 2) of the cylindrical portion 141. At the center of the closing plate 142, a through hole 142a is formed through which the fitting protrusion 133 of the rotary member 130 described above is inserted. A peripheral wall 142b that protrudes in the direction opposite to the base 110 (rightward in FIG. 2) is formed at the peripheral edge of the through hole 142a.

  Further, as shown in FIG. 3, the slide member 140 has three L-shaped fixed contacts 143 (143a, 143b) so as to straddle the inner peripheral surface of the cylindrical portion 141 and the inner surface of the closing plate 142. , 143c). As shown in FIG. 4, these three fixed contacts 143 are evenly arranged in a range from the vehicle rearward direction to the vehicle downward direction on the inner peripheral surface of the cylindrical portion 141 along the clockwise direction. .

  More specifically, the first fixed contact 143a, which is the first fixed contact among these fixed contacts 143, is arranged in the vehicle rearward direction. The second fixed contact 143b, which is the second fixed contact, is arranged in the middle between the vehicle rear direction and the vehicle lower direction. The third fixed contact 143c, which is the third fixed contact, is arranged in the vehicle downward direction. In this way, the fixed contacts 143 are evenly arranged.

  A common contact 144 is assembled along the circumferential direction in the inner surface of the closing plate 142 in a range facing the three fixed contacts 143. The common contact 144 can be electrically connected to one of the three fixed contacts 143 through the short-circuit piece 134 already described. Then, when the knob 190 is rotated about the axis in the assembled state of the sheet switch to be described later, the short-circuit piece 134 rotates, so that the fixed contact 143 that is electrically connected to the common contact 144 is switched to the desired fixed contact 143. be able to. The fixed contacts 143 and the common contacts 144 are electrically connected to the control device via cable wiring.

  Here, an example of switching the fixed contact 143 will be described. As shown in FIG. 5, for example, the knob 190 is rotated so that the tip of the knob 190 faces the rear of the vehicle (hereinafter referred to as “to face the position P1”). When the knob 190 is rotated, the first fixed contact 143a and the common contact 144 are electrically connected by the short-circuit piece 134. As a result, among the four electric functions already described, the control circuit for operating the tilt up / down function A in the control device is turned on.

  Similarly, the knob 190 is rotated so that the tip of the knob 190 is directed between the vehicle rearward direction and the vehicle downward direction (hereinafter, “the knob 190 is rotated toward the position P2”). 2), the second fixed contact 143b and the common contact 144 are electrically connected by the short-circuit piece 134. Thereby, the control circuit which operates the lumbar support function B in the control device among the four electric functions already described is turned on.

  Similarly, when the knob 190 is rotated so that the tip of the knob 190 is directed downward in the vehicle (hereinafter referred to as “the knob 190 is rotated so as to face the position P 3”), the short-circuit piece 134. Thus, the third fixed contact 143c and the common contact 144 are electrically connected. Thereby, the control circuit which operates the headrest raising / lowering function C and the reclining function D in the control device among the four electric functions already described is turned on. By rotating the knob 190 in this manner, desired electric functions A, B, C, and D can be operated.

  Returning to FIG. 2, the case 150 includes a ring-shaped cylindrical portion 151 and a suitable closing plate 152 that closes one end (right end in FIG. 2) of the cylindrical portion 151. Engaging claws 153 and 153 that can be fitted into the engaging holes 111 of the base 110 described above are formed on the periphery of the other end (left end in FIG. 2) of the cylindrical portion 151. Further, the inner diameter of the cylindrical portion 151 is set to be substantially the same as the outer diameter of the cylindrical portion 121 of the receiving member 120 already described.

  A through hole 152 a is formed at the center of the closing plate 152. The outer diameter of the through hole 152a is determined by sliding the knob 190 in the vehicle front-rear direction and the vehicle vertical direction and pressing the outer peripheral surface of the slide member 140 in the assembled state of the seat switch described later. It is set to be able to operate. Also, a first pin 152b and a second pin 152c project from the surface of the closing plate 152 at the lower position and the right position toward the through hole 152a, respectively.

  The first pin 152b is one end of the tip 172 of the stopper 170 that is rotated integrally with the knob 190 when the knob 190 is rotated toward the position P3 in the assembled state of a sheet switch to be described later. It protrudes so that it may be pressed against the wall surface 172a. Similarly, the second pin 152c is a stopper 170 that rotates together with the knob 190 when the knob 190 is rotated toward the position P1 in an assembled state of a sheet switch to be described later. It protrudes so as to be pressed against the other wall surface 172b of the tip 172.

  The stopper 170 is formed in a long lever shape, and a through hole 171 is formed at one end thereof. The through hole 171 has a semicircular shape into which the semicircular portion 133 of the fitting protrusion 133 of the rotating member 130 described above can be fitted. Further, the above-described tip 172 is formed at the other end of the operation member 170.

  The shield member 180 is a member having a design surface formed in a panel shape covering the side portion of the seat cushion 10. The shield member 180 is formed with a through-hole 181 through which the fitting protrusion 133 of the rotary member 130 already described is inserted.

  The knob 190 is formed in a long lever shape, and a fitting groove 191 in which the semicircular portion 133b of the fitting protrusion 133 of the rotating member 130 described above can be fitted is formed on the inner surface of one end thereof. . Of the peripheral edge 190a of the knob 190, the edge 190b facing the shield member 180 is not in contact with the shield member 180 even when the knob 190 is rotated and slid. It is set to have a gap.

  Next, referring to FIG. 2, the base 110, the receiving member 120, the rotating member 130, the slide member 140, the case 150, the stopper 170, the shield member 180, and the knob 190 are configured. A method for assembling the seat switch is described.

  First, the rotary member 130 is assembled inside the slide member 140 so that the fitting protrusion 133 of the rotary member 130 protrudes from the through hole 142a of the slide member 140. At this time, as shown in FIG. 4, the rotating member 130 is assembled at a position where the short-circuit piece 134 is in a state where the third fixed contact 143 c and the common contact 144 are electrically connected.

  Next, the slide member 140 is assembled inside the receiving member 120. At this time, between the inner peripheral surface of the receiving member 120 and the outer peripheral surface of the slide member 140, the switches S1 to S4 provided on the outer peripheral surface of the receiving member 120 are always pressed by the outer peripheral surface of the slide member 140. As a result, the four compression springs 123 are assembled evenly in the circumferential direction. Thus, the switches S1 to S4 are operated only when the seated person slides the slide member 140.

  Thereafter, the receiving member 120 is assembled inside the case 150 so that the fitting protrusion 133 of the rotating member 130 protrudes from the through hole 152a of the case 150. At this time, as already described, since the inner diameter of the cylindrical portion 151 of the case 150 is substantially the same as the outer diameter of the cylindrical portion 121 of the receiving member 120, the receiving member 120 is integrated with the case 150. Is retained. Thereafter, the engaging claw 153 of the case 150 is fitted into the engaging hole 111 of the base 110, and the case 150 is held integrally with the base 110.

  At this time, the receiving member 120, the rotating member 130, and the slide member 140 are assembled inside the case 150 so that there is no backlash in the axial direction. At this time, as already described, the short-circuit piece 134 is in a bent state. Therefore, due to the reaction force of this bending, the short-circuit piece 134 and the third fixed contact 143c, and the short-circuit piece 134 and the common contact 144 are electrically connected in a pressure contact state. The same applies to all the fixed contacts 143.

  Thereafter, the through hole 171 of the stopper 170 is fitted into the semicircular portion 133 b of the fitting protrusion 133 of the rotating member 130 disposed in the through hole 152 a of the case 150. Accordingly, when the rotating member 130 is rotated in the direction around the axis of the fitting protrusion 133, the stopper 170 is also rotated with this rotation. At this time, the shapes of the fitting hole 111 and the semicircular part 133b are set so that the tip of the stopper 170 faces the vehicle downward direction. At this time, one wall surface 172a of the tip 172 of the stopper 170 is in contact with the first pin 152b on the surface of the case 150. Thereafter, the shield member 180 is assembled to a support base (not shown) of the seat cushion 10 in a state where the fitting protrusion 133 of the rotating member 130 protruding from the through hole 152a of the case 150 is inserted into the through hole 181 of the shield member 180. .

  Finally, the fitting groove 191 of the knob 190 is fitted into the semicircular portion 133 b of the fitting projection 133 of the rotating member 130 protruding from the through hole 181 of the shield member 180. At this time, the shapes of the fitting groove 191 and the semicircular portion 133b are set so that the tip of the knob 190 faces the vehicle downward direction. When the knob 190 is rotated in the direction around the axis of the fitting protrusion 133, the rotating member 130 and the stopper 170 are also rotated with this rotation. This description states that “the knob of the seat cushion is rotated so as to rotate about an axis having the vehicle width direction as an axial direction and to slide and move in the vehicle longitudinal direction and / or the vehicle vertical direction via the axis. This is equivalent to the description of “equipped in an eccentric manner on one side portion via a shaft”.

  Finally, with reference to FIGS. 6 to 12, a method of using the above-described seat switch will be described. This seat switch is used in such a manner that after the knob 190 is turned to select a desired electric function A, B, C, D, the selected electric function A, B, C, D is operated.

  When it is desired to move the front portion of the seat cushion 10 upward from the state in which the knob 190 faces the position P3 (see FIG. 6), the seated person first turns the knob 190 to face the position P1. (See FIG. 7). When the knob 190 reaches the position P1, the seated person next performs an operation of sliding the knob 190 upward in the vehicle. As the slide moves, the slide member 140 also moves upward in the vehicle against the compression spring 123 (see FIG. 8). With this movement, the outer peripheral surface of the slide member 140 presses the switch S3, so that the switch S3 is in an operating state. As a result, the power circuit for moving the front portion of the seat cushion 10 in the vehicle upward direction in the power circuit in the control device is turned on, and the front portion of the seat cushion 10 is slid in the vehicle rear direction by the driving means. I will do it.

  On the contrary, when the front part of the seat cushion 10 is desired to move downward in the vehicle, the seated person performs an operation of sliding the knob 190 downward in the vehicle (see FIG. 9). As a result, the front portion of the seat cushion 10 is slid downward in the vehicle by the driving means, similarly to the case where the front portion of the seat cushion 10 is moved upward in the vehicle. When the front part of the seat cushion 10 is desired to move in the vehicle longitudinal direction, the seat occupant moves the knob 190 in the vehicle longitudinal direction as in the case where the front part of the seat cushion 10 is moved in the vehicle vertical direction. It is only necessary to perform an operation of sliding to.

  Here, when the seated person releases the operation of the knob 190 (the seated person releases his hand from the knob 190), the knob 190 is returned to the position before the operation by the restoring force of the compression spring 123. As a result, the power circuit for moving the front portion of the seat cushion 10 in the vehicle downward direction in the power circuit in the control device is turned off, and the moving operation of the front portion of the seat cushion 10 is stopped (see FIG. 7). ).

  Further, from this state, for example, when the seat back 20 is to be tilted forward in the vehicle, first, the seated person moves the position P3 in the same manner as when the front part of the seat cushion 10 is moved upward in the vehicle. The knob 190 is rotated so as to face (see FIG. 10). When the knob 190 reaches the position P3, the seated person then performs an operation of sliding the knob 190 in the forward direction of the vehicle. Then, along with this sliding movement, the sliding member 140 also moves in the vehicle forward direction against the compression spring 123 (see FIG. 11). With this movement, the outer peripheral surface of the slide member 140 presses the switch S1, so that the switch S1 is in an operating state. As a result, the power circuit for tilting the seat back 20 in the vehicle front direction in the power circuit in the control device is turned on, and the seat back 20 is tilted in the vehicle front direction by the driving means.

  On the contrary, when the seat back 20 is desired to be tilted backward in the vehicle, the seated person performs an operation of sliding the knob 190 in the forward direction of the vehicle (see FIG. 12). As a result, the seat back 20 is tilted in the rearward direction of the vehicle by the driving means in the same manner as when the seat back 20 is tilted in the forward direction of the vehicle. Note that when the headrest 30 is to be lifted or lowered, the seated person may perform an operation of sliding the knob 190 in the vehicle vertical direction as in the case where the seat back 20 is tilted in the vehicle front-rear direction.

  Here, when the seated person releases the operation of the knob 190 (the seated person releases his hand from the knob 190), the knob 190 is returned to the position before the operation by the restoring force of the compression spring 123. As a result, the power circuit for tilting the seat back 20 in the vehicle rearward direction in the power circuit in the control device is turned off, and the tilting operation of the seat back 20 is stopped (see FIG. 10).

  Even when the knob 190 is directed to the position P2, as in the case where the knob 190 is directed to the positions P1 and P3, the seated person slides the knob 190 in the vehicle front-rear direction or the vehicle up-down direction, as desired. The electric function B can be activated.

  The vehicle seat switch according to the embodiment of the present invention is configured as described above. According to this configuration, when it is desired to tilt the seat back 20 in the forward direction of the vehicle, the seat occupant rotates the knob 190 so that its tip (lower end) faces downward in the vehicle. Is being slid in the forward direction of the vehicle. At this time, one wall surface 172a of the tip 172 of the stopper 170 is in contact with the first pin 152b of the case 150. Therefore, when the knob 190 is slid in the vehicle front direction, the first wall 172a is in contact with the first pin 152b of the case 150. The knob 190 rotates about the axis of the pin 152b in the forward direction of the vehicle (see FIG. 11). This description is described in the claims. “When the knob is slid in the forward direction of the vehicle with the knob rotated so that the tip is directed downward of the vehicle, the sliding movement is converted into a forward tilt of the vehicle. Is equivalent to.

Therefore, the movement of the knob 190 to be operated is the same as the movement of the vehicle seat when the seat back 20 is tilted in the forward direction of the vehicle (the movement of the knob to be operated is also a rotational movement, Since the movement of the vehicle seat when the vehicle 20 is tilted forward is also a movement of the vehicle), the seated person can operate the knob 190 without feeling uncomfortable.

  Further, according to this configuration, when it is desired to move the front portion of the seat cushion 10 in the upward direction of the vehicle, the seat occupant rotates the knob 190 so that the tip (lower end) thereof faces the rear of the vehicle. The operation of sliding the knob 190 upward in the vehicle is performed in the moving state. At this time, similarly to the one wall surface 172 a of the tip 172 of the stopper 170 described above, the other wall surface 172 b of the tip 172 of the stopper 170 is in contact with the second pin 152 c of the case 150. When the knob 190 is slid in the vehicle upward direction, the knob 190 rotates in the vehicle upward direction around the axis of the second pin 152c (see FIG. 8). This description is described in the claims. “When the knob is slid in the upward direction of the vehicle with the knob rotated so that the tip is directed toward the rear of the vehicle, the sliding movement is converted into a tilt in the upward direction of the vehicle. Is equivalent to.

  Therefore, the movement of the knob 190 to be operated is the same as the movement of the vehicle seat when the front portion of the seat cushion 10 is moved in the upward direction of the vehicle (the movement of the knob to be operated is also a rotational movement). Since the movement of the vehicle seat when the front part of the seat cushion 10 is moved upward is also a rotation movement), the seated person can operate the knob 190 without feeling uncomfortable.

(Example 2)
Next, Example 2 will be described with reference to FIG.
FIG. 13 is an exploded perspective view of a seat switch according to another embodiment (Example 2). As apparent from FIG. 13, the second embodiment is an embodiment in which the stopper 170 is integrally assembled with the knob 190 as compared with the first embodiment already described. In the following description, members having the same or equivalent configuration as those of the first embodiment are denoted by the same reference numerals in the drawings, and redundant description is omitted.

  In the second embodiment, the length of the first pin 152b on the surface of the case 150 is set longer than the length described in the first embodiment. For this reason, the shield member 180 is formed with a through hole 182 for allowing the first pin 152b to pass therethrough. Further, a stopper portion 192 projects from the inner surface of the knob 190. The surface 192a of the stopper portion 192 is configured to contact the first pin 152b protruding from the surface of the case 150, like the one wall surface 172a of the tip 172 of the stopper 170 described in the first embodiment. Therefore, also in the second embodiment, the movement of the knob 190 to be operated is the same as the movement of the vehicle seat when the seat back 20 is tilted in the front direction of the vehicle, as in the first embodiment. The seated person can operate the knob 190 without feeling uncomfortable.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the embodiment, the case where the tip of the knob 190 rotates in the range from the vehicle lower direction to the vehicle rear direction has been described. However, the present invention is not limited to this, and the end of the knob 190 may be rotated in the range from the vehicle upward direction to the vehicle rearward direction. In that case, on the surface of the closing plate 152 of the case 150, the upper position and the right position toward the through hole 152a correspond to the first pin 152b and the second pin 152c described in the first embodiment. What is necessary is just to project 3 pins and 4th pins. Then, similarly to the description of the first embodiment, the seated person can operate the knob 190 without feeling uncomfortable.
