Seat base sliding apparatus
View Patent ↗The present disclosure discloses a seat base sliding device applied to a seat of a heavy machinery such as a loader, an excavator, or the like. The seat base sliding device includes: a seat base with a lower part is fixed to a floor of a vehicle body and an upper part at which a seat is installed; a sliding plate slidable inwards and outwards in a lateral direction of the seat base at both left and right sides of the seat base and in which a control stand is fixed to one side thereof; and at least one adjustment unit selectively fixing the sliding plate of which the position is determined by sliding movement to the seat base. The present disclosure is capable of preventing a cabin from knocking against both control stands of a seat device at the time of assembling the cabin around the seat device and in addition, preventing the corresponding control stands from interfering in a thigh of a driver at the time of operating a control lever of each control stand laterally after assembling the cabin.
1. A seat base sliding device, comprising:
a seat base including a lower part fixed to a floor of a vehicle body and an upper part fixed to a seat;
a sliding plate, which a control stand is fixed to one side thereof, located on left and right sides of the seat base and slid according to a lateral direction of the seat base; and
at least one adjustment unit selectively fixing the sliding plate to the seat base at a certain position determined by sliding movement of the sliding plate, wherein;
the sliding plate includes a horizontal section fixed to each of both left and right sides of the seat base through at least one adjustment unit and an inclined section slantly connected with the horizontal section, and the control stand is connected to one side of the inclined section.
2. The seat base sliding device according to claim 1 , wherein each adjustment unit includes the seat base having a through hole, the sliding plate having a slot extending laterally, and an adjustment member penetrating the slot of the sliding plate to fit in the through hole of the seat base, and
the adjustment member selectively presses at least one of the seat base and the sliding plate and is fixed thereto to selectively maintain an interpressing state of the seat base and the sliding plate.
3. The seat base sliding device according to claim 2 , further comprising:
a screw section a formed at one side of each adjustment member;
a nut fixed to a lower part of the through hole and coupled with the screw section; and
a cap nut further coupled with the end of the screw section penetrating the nut when the screw section and the nut are coupled with each other to set an opening limit of the adjustment member.
