Description

  The present invention relates to an attachment / detachment assistance device for a vehicle seat.

  For example, when cleaning a front seat of a vehicle such as an automobile, or repairing a failure of a power seat (a seat that can be adjusted by sliding forward and backward and tilting the backrest by electric power) The front seat may be removed. In addition, after the cleaning or repair is completed, the front seat needs to be attached to the vehicle body again.

  Thus, when removing a seat from a used vehicle or attaching a seat to a vehicle body, conventionally, an operator manually removes and attaches the seat.

On the other hand, when a new vehicle is manufactured, a seat is automatically attached to the vehicle body using an automatic mounting device in a manufacturing factory (see, for example, Patent Document 1). This automatic mounting apparatus includes a gantry arranged and fixed along a conveyance line of a vehicle body, and various robots for mounting a sheet and the like arranged on the gantry.
