Claims

[Scope of Claim for Utility Model Registration] (1) A footrest that can be stored in and out of the seat of a seat, which is guided along a slide rail provided in the seat and can be stored in and out of the seat. A base plate whose front end is supported on the floor when taken out from inside the seat, and a footrest portion on the upper surface supported by first and second link mechanisms connected to the base plate side. a footrest body formed with a footrest body, a guide member formed on the board in parallel with the direction of entry and exit of the board, and having a long hole in a part thereof for guiding the lower end of the first link mechanism substantially horizontally; The driving body is provided close to the guide member and is moved along the guide direction of the guide member by an actuation mechanism to drive the first and second link mechanisms. footrest for seats. (2) The driving body is movable with respect to a guide path fixed on the substrate, and the driving mechanism rotates a threaded rod that is screwed into a threaded member provided on a part of the driving body. The driving body is configured to move with respect to the substrate by causing the driving body to move by a predetermined distance with respect to the substrate, and a part of the first link mechanism is connected to the driving body, and the driving body moves a predetermined distance with respect to the substrate. 2. The footrest for a seat according to claim 1, wherein a part of the second link mechanism comes into contact with the driving body to drive the second link mechanism. (3) The footrest for a seat according to claim 1 or 2, wherein the threaded rod is at least one. (4) The first link mechanism is configured such that its lower end is rotatably connected to a part of the driving body, and that this lower end is guided into an elongated hole formed on the substrate side, and The footrest for a seat according to any one of claims 1 to 3, wherein the upper end is rotatably connected to the rear end side of the footrest main body. (5) The second link mechanism includes a rotation shaft supported horizontally by the guide member, and a rotation shaft that is fixed to the rotation shaft so that when the front end of the driver comes into contact with the lower end of the rotation shaft, the rotation shaft and a connecting arm whose front end is connected to the rear end of the actuating arm and whose rear end is connected to the footrest main body. The footrest for a seat according to any one of items 1 to 4. (6) A drive mechanism for moving the board in and out of the sheet includes a drive arm, one end of which is engaged in a push elongated hole provided in the board, and the other end of the drive arm connected to the drive mechanism. Utility model registration claim 1, comprising a drive member that drives a drive arm, and a pivot support that rotatably supports the drive arm with respect to a floor surface to which the seat is fixed. The footrest for a seat according to any one of items 1 to 5. (7) A drive mechanism for moving the board in and out of the seat includes a drive screw shaft whose one end is rotatably connected to the board, a gearbox that rotatably supports the other end of the drive screw shaft, and A footrest for a seat according to any one of claims 1 to 5, characterized in that it comprises a drive motor connected to a gearbox via a clutch.
