The front and back of the knob can be recognized by the hand, making it easier to operate the knob.

  FIG. 1 shows an overall external view of a power seat 1 according to the present invention. The power seat 1 is a seat on the driver's seat side, and the seat base 5 slides in the vehicle front-rear direction 51 on a seat rail (not shown) fixed to the vehicle body. A seat surface portion 4 is provided on the upper surface of the seat base 5, a backrest portion 3 is provided at a rear portion of the seat base 5 so as to be tiltable, and a headrest 2 is provided above the backrest portion 3. A plurality of electric motors (not shown) are provided in the skeleton inside the power seat 1, and the seat base 5 can be slid in the front-rear direction 51 of the vehicle by driving the electric motor. A reclining operation is possible in the tilt direction 31. The power seat switch (knob) 10 is provided in a recessed portion formed on the right side of the seat base 5 and is operated with the right hand by the driver.

  Next, details of the power seat switch 10 will be described. 2A shows an enlarged schematic diagram of the power seat switch portion of the first embodiment in FIG. 1, and FIG. 2B shows an enlarged schematic diagram when the knob 10 is removed in FIG. 2A. The figure is shown. 2A and 2B, the right side corresponds to the front of the vehicle or the seat.

  In FIG. 2A, the knob 10 is a substantially rectangular parallelepiped resin knob composed of a front part 101, a center part 12, and a rear part 103 from the front. The knob can be pulled up 31a and pushed down 31b by the driver, the rear part 103 can be pulled up R and pushed down M, and can be slid 51a in the longitudinal direction of the seat. Is possible.

  FIG. 2 (B) shows an internal contact portion from which the knob 10 in FIG. 2 (A) is removed, and front contacts 101a and 101b are provided in the vertical direction as electrical contacts on the seat base 5 side. Rear contacts 103a and 103b are provided in the vertical direction, and center contacts 102a and 102b are provided in the horizontal direction. The movement of the operated knob 10 causes the front protrusion 101c, the center protrusion 102c, and the rear protrusion 103c, which are protrusions provided on the knob 10, to move and press the corresponding contacts, thereby physically within each electrical contact. The contact is connected and switched on and off. The protrusions 101c, 102c, and 103c are integrally formed with the knob 10 from a resin and project toward the contact side. The protrusions 101c, 102c, and 103c move as the knob 10 is operated to press the corresponding contact.

  A series of flow from the operation of the knob 10 to the operation of the power seat 1 in the first embodiment will be described. First, the case where the backrest part 3 of the power seat 1 is tilted backward will be described. The front part 101 of the knob 10 is pulled up by the driver, and the knob 10 rotates in the direction 31a. By this rotation, the front protrusion 101c presses the front contact 101a, and the contact comes into physical contact within the front contact 101a, and is electrically turned on. This on signal is detected by a power seat ECU (not shown), and a voltage is supplied from the power supply so that the reclining motor (not shown) of the backrest part 3 is driven in such a direction that the backrest part 3 tilts backward, The backrest 3 is inclined backward. Since power is supplied to the motor only when the front contact 101a is in the ON state, the backrest 3 falls to the rear 31 only during the period when the front portion 101 of the knob 10 is pulled up. When raising the backrest part 3 forward, the backrest part 3 rises forward 31 by pushing down 31 b of the front part 101 of the knob 10. As in the case of tilting backward, the front contact 101b is pressed by the front projection by the push-down 31b of the knob 10, and the contact is connected in the contact. The backrest 3 is raised to the front 31.

  A case where the power seat 1 is slid forward will be described. When the driver slides the knob 10 forward of the power seat 1, the center contact 102a is pressed by the center protrusion 102c, the contact is physically connected within the contact 102a, and is electrically turned on. This ON state is detected by the power seat ECU, and a voltage is supplied to a sliding motor (not shown) in a direction to slide the power seat 1 forward, and the power seat 1 moves forward by driving the sliding motor. . When it is desired to move the power seat 1 rearward, by sliding the knob 10 rearward, the center protrusion 102 presses the center contact 102b and the on state of the center contact 102b is detected, and the power seat is driven by driving the slide motor. 1 slides backward.

  The driver operates the power switch 10 on and off because it operates only during a period in which the electrical contacts 101a, 101b, 102a, and 102b corresponding to the reclining operation 31 and the sliding operation 51 of the power seat 1 are detected. Thus, the reclining operation 31 and the sliding operation 51 of the power seat 1 can be controlled.

  Next, a description will be given of a case where the slide position and reclining posture of the power seat 1 are stored by operating the knob 10 and a previously stored slide position and reclining posture are reproduced.

  When storing the slide position and the reclining posture, the driver slides and reclines the power seat 1 by operating the knob 10 so that the power seat 1 is in a safe sliding position and reclining posture suitable for the physique and sitting of the driver. Adjust the position and posture. Thereafter, the driver presses the rear portion 103 of the knob 10 to cause the memory function to function. At this time, the rear protrusion 103c of the knob 10 presses the rear contact 103b, and the contact is physically brought into contact with the rear contact 103b to be turned on. When the power seat ECU detects this ON state, the ECU detects the position from the stroke sensor for sliding operation (not shown), the position from the stroke sensor for reclining operation (not shown), the posture signal (information), the sliding operation end, The position and posture of the power seat 1 are estimated and stored from information such as the energization time to the motor from the reclining operation end. Thereafter, as a general dismounting procedure, the driver slides the power seat 1 rearward so that it is easy to dismount, falls the backrest 3 backward, disembarks, turns off the ignition, and removes the key.

  When reproducing the previous slide position and reclining posture, the driver gets on and pulls up the rear portion 103 of the knob 10 to cause the reproduction function to function. At this time, the rear protrusion 103c of the knob 10 presses the rear contact 103b, and the contact comes into physical contact within the rear contact 103b and is turned on. When the power seat ECU detects this ON state, the ECU energizes the motor so as to coincide with the stored slide position and reclining attitude, and sets the power seat 1 to the stored slide position and reclining attitude.

  A second embodiment will be described with reference to FIGS. 3 (A) and 3 (B). FIG. 3A shows an enlarged schematic view of the power seat switch portion of the second embodiment, and FIG. 3B shows an enlarged schematic view when the knob 10 is removed in FIG. 3A. ing. The second embodiment is an embodiment in which the roles of the front contacts 101a and 101b and the rear contacts 103a and 103b are exchanged in the first embodiment.

  3 (A) and 3 (B), the pull-up R and push-down M operations of the front part 101 of the knob 10 correspond to the storage and reproduction of the slide position and reclining posture of the power seat 1 in the longitudinal direction, The operation of pulling up 31 a and pushing down 31 b of the rear part 103 corresponds to the reclining operation of the power seat 1. Except for the configuration of the contacts, the configuration is the same as that of the first embodiment, and thus the description thereof is omitted.

  A third embodiment will be described with reference to FIGS. 4 (A) and 4 (B). Since the configuration of the contact shown in FIG. 4B is the same as that of the second embodiment, the description thereof is omitted. The third embodiment is different from the other embodiments in the shape of the knob 10, and as shown in FIG. 4A, the rear portion 103 on the rear side of the vehicle is bent obliquely upward. Yes. Since the knob 10 is bent in this way, when the driver sits on the power seat 1 and operates, the right seat touches the power seat switch 10 between the vehicle door and touches any part of the knob 10. It is possible to prevent the front part 101 and the rear part 103 from being operated by mistake. Further, since the rear portion 103 is bent obliquely upward, it is easy to imagine the backrest portion 3 of the power seat 1, and it is relatively easy even if operated by a person who is not operated. It can be recognized that the pulling 31a and pushing 31b operations correspond to the reclining operation of the power seat 1, and it is easy to operate. In this embodiment, the knob 10 has a shape that makes it easy to recognize the front part 101 and the rear part 103 of the knob 10 by bending the rear rear part 103 obliquely upward. However, other shapes can be applied as long as the front part 101 and the rear part 103 can be easily identified. Further, the knob 10 may be provided with a protrusion or a recess.

  As described above, in these three embodiments, in storing and reproducing the slide position and reclining posture of the power seat 1, the storage function and the reproduction function are detected in a state in which the knob 10 is operated and stored, and the contact ON state corresponding to the reproduction is detected. However, even if the timer is provided so as to function when the ON state of the contact is detected for a predetermined time and the malfunction due to an erroneous operation of the knob 10 is reduced, it does not depart from the idea of the present invention.

  In addition, the upper contact is set for the first person and the lower contact is for the second person, and the slide position and reclining posture of the power seat 1 are stored and reproduced according to the duration of the contact ON state. Also good.

  Furthermore, it is configured to function as a memory and a playback when switching between on and off of the rear contacts 103a and 103b is detected a plurality of times in succession, and the position and orientation of the power seat 1 that can be stored according to the number of times are set. However, there is no problem with a configuration in which a memory / reproduction function (memory function) is added corresponding to a plurality of drivers.

  According to the present invention, the power seat slide 10 and the reclining operation can be controlled on and off with one power seat switch 10 (knob), and the memory function can be operated. Can be provided. Further, since the memory function switch is provided on the seat base 5, wiring is not required as compared with the case where the memory function switch is arranged on the door panel, and the switch 10 of the power seat 1 having the memory function is provided. it can.
