  • the lock lever 22 rotates about the support shaft 21 by the coil spring 24 and the lock pin 27 engages in the “passenger's getting on-and-off” lock groove 26 C thereby locking the seat 1 in the “passenger's getting on-and-off” rotating position. If rotating the seat 1 while stopping pulling up the lock lever 22 , the lock pin 27 engages in the “passenger's getting on-and-off” lock groove 26 C at the same time when the lock pin 27 faces the groove 26 C.
  • the “passenger's getting on-and-off” rotating position is mainly utilized in getting on-and-off the vehicle, forming a seat-rotating position facilitating an operator's getting on-and-off the vehicle.

  • FIG. 16 shows the structure of an electrical circuit.
  • a manipulation amount about the accelerator lever 10 is inputted to a rotary encoder 51 through a rod 50 . Then, the rotary encoder 51 converts the manipulating amount about the accelerator lever 10 to an electric signal and further outputs the signal to a controller 52 .
  • a manipulation amount about the accelerator pedal 7 is inputted to a rotary encoder 54 through a rod 53 . Then, the rotary encoder 54 converts the manipulating amount about the accelerator pedal 7 to an electric signal and further outputs the signal to the controller 52 .
  • the rotary encoder 51 for the accelerator lever 10 is connected with the rotary encoder 54 for the accelerator pedal 7 , as shown in FIG. 16.
  • the encoders 51 , 54 include variable resistances 51 A, 54 A to which voltages are applied from the controller 52 , respectively. Output voltages from the variable resistances 51 A, 54 A are respectively inputted to a switching relay 55 .
  • the switching relay 55 outputs an output of the rotary encoder 54 , which corresponds to the manipulating amount of the accelerator pedal 7 , to the controller 52 when a built-in solenoid 55 A is not excited.
  • the switching relay 55 While, when the solenoid 55 A is excited, the switching relay 55 outputs an output of the rotary encoder 51 , which corresponds to the manipulating amount of the accelerator lever 10 , to the controller 52 .
  • the solenoid 55 A of the switching relay 55 is connected to the seat-rotating switch 43 and therefore, the relay 55 is activated when the switch 43 operates.
  • the seat-rotating switch 43 When the seat-rotating switch 43 is turned off, a signal corresponding to a manipulating amount of the accelerator pedal 7 is inputted to the controller 52 .
  • the controller 52 operates a traveling motor 56 or a brake 57 corresponding to the above signals, thereby controlling the traveling condition of the vehicle.
  • the switching relay 55 since the switching relay 55 generates a signal corresponding to the manipulating amount of the accelerator lever 10 to the controller 52 when the seat-rotating switch 43 detects the seat 1 being rotated to the backward traveling position, an operator can manipulate the accelerator lever 10 on the lock lever 22 while identifying obstacles etc. existing in the backward traveling direction without collapsing an operator's driving posture, thereby allowing a vehicle's traveling condition to be controlled corresponding to an operator's manipulation.
  • the switching relay 55 Since the switching relay 55 generates a signal corresponding to the manipulating amount of the accelerator pedal 7 to the controller 52 when it is detected due to the inactivation of the seat-rotating switch 43 that the seat 1 is in the neutral rotating position or the “passenger's getting on-and-off” rotating position, an operator can control a vehicle's traveling condition corresponding to an operator's manipulation on the accelerator pedal 7 while identifying obstacles etc. existing in the forward traveling direction.
  • the seat 1 is equipped, in place of the accelerator pedal 7 , with the accelerator lever 10 (as the accelerator manipulating unit) allowing a vehicle traveling unit to be controlled manually. Therefore, even when an operator is getting on the seat 1 , the operator can control the vehicle traveling unit by the accelerator lever 10 manually, allowing a rotating angle of the seat 1 to be increased without taking operationality about the accelerator pedal 7 into consideration. Thus, it is possible to rotate the seat 1 up to an ideal angle required to ensure field of vision at a vehicle's backward traveling, whereby an operator's fatigue due to a strained driving posture can be reduced remarkably.
  • the rotating mechanism 5 is formed by the bearing 17 that supports the rotating plate 16 to the base plate 15 rotatably and the low-friction sheet 18 disposed between the base plate 15 and the rotating plate 16 through a clearance while surrounding the bearing 17 , the rotating mechanism 5 can be thinned as a whole, whereby it is possible to suppress raising of a hip point about the seat 1 to the utmost.
  • a load applied on the seat 1 is mostly born by the bearing 17 , while the low-friction sheet 18 bears the load only when the rotating plate 16 is bent. Therefore, the seat 1 can be rotated by only twisting an operator's body slightly, thereby requiring no motive energy to rotate the seat 1 .
  • the position of the rotating plate 16 in relation to the base plate 15 can be altered at least between the neutral position and the retreat rotating position and also locked up in each of the neutral position and the retreat rotating position.
  • the lock lever 22 for releasing these locking states is equipped with the accelerator lever 10 as the accelerator manipulating unit. Therefore, it is possible for an operator to manipulate the accelerator lever 10 while gripping the lock lever 22 after the rotation of the seat 1 has been completed, whereby a smooth shifting to the backward traveling can be accomplished, thereby improving the operating efficiency of an operator.
  • the position of the rotating plate 16 can be altered to the “passenger's getting on-and-off” rotating position on the opposite side of the retreat rotating position over the neutral position and also locked up in the “passenger's getting on-and-off” rotating position. Therefore, when the rotating plate 16 is in the “passenger's getting on-and-off” rotating position, the seat 1 faces in the “passenger's getting on-and-off” direction, whereby the passenger's boarding and alighting capability can be improved remarkably.
  • the seat apparatus of the embodiment is effective for the latest mainstream hip-support seat for holding an operator.
  • the rotating mechanism 5 is disposed between the seat slide mechanism 4 and the seat 1 , the relationship between a hip point of the seat 1 and its rotating center is usually fixed irrespective of the sliding position of the seat 1 , thereby producing no operator's sense of discomfort in rotating the seat 1 and also producing a constant power necessary for an operator to rotate the seat 1 .
  • the seat apparatus of the embodiment enables an operator to manually operate the vehicle traveling unit by means of the accelerator lever 10 as the accelerator manipulating unit when the seat 1 is positioned in the retreat rotating position, it is possible to prevent an operator's wrong operation at a vehicle's forward movement etc., thereby improving safety.
  • the seat apparatus is constructed so that an operator can control the traveling of an industrial vehicle with a throttle valve for drive control by means of the accelerator lever 10 (as the accelerator manipulating unit) communicated with the throttle valve through an accelerator wire 11 , the seat apparatus is suitable for an industrial vehicle, such as fork lift equipped with an engine, and is available at a popular price.
  • the seat apparatus is adapted so as to generate a signal corresponding to an operator's manipulating amount for accelerator lever 10 (as the accelerator manipulating unit) to the controller 52 . Accordingly, the seat apparatus of the modification is suitable for an electrically-operated industrial vehicle, such as battery-type fork lift. Furthermore, the seat apparatus is available at a popular price and also easy in layout.
