A vehicle seat including a seat that includes a seat cushion and a seat back; an inclination drive portion configured to incline the seat back; and a slide mechanism configured to enable the seat to slide in a vehicle front-rear direction, in which the slide mechanism includes: a slide rail supporting to be able to move in a sliding manner in the front-rear direction; a slide drive portion configured to enable the upper rail to slide with respect to the lower rail; and a mode switching switch configured to enable mode switching, in the normal mode, a slide amount used by the seat when the vehicle is driven is used, in the relaxing mode, a slide amount at a position rearward with respect to the rearmost end in the normal mode is used, and, when the relaxing mode is switched to the normal mode, in a case where the seat back is inclined, the seat back is raised to the normal mode, and then the seat is moved forward to the normal mode.

A method of manufacturing a connecting rod is provided. The method includes the steps of (1) forming, on a long rod material, a rotation transmitting portion having a non-circular cross section; (2) cutting the rod material to provide the rotation transmitting portion at each of both ends; and (3) forming, by cutting work, a small-diameter column portion and a tapered portion at a first end of the cut rod material from a tip-end side. The small-diameter column portion has a diameter smaller than a diameter of the rotation transmitting portion. The tapered portion is provided continuously from the small-diameter column portion and gradually increases in diameter. The rotation transmitting portion is provided continuously from the tapered portion.

A seat (1) for transport vehicles with an articulated frame (2) capable of moving and changing shape between a neutral position N and a comfort position C, which comprises a headrest portion (21) mechanically linked by means of a connector (22) to a connection area of a backrest portion (23) that changes the height position thereof as the frame (2) moves from the neutral position N to the comfort position C thereof, the connector (22) being suitable for this change in height position to be transmitted, by means of mechanical drag, to the headrest portion (21), the headrest portion (21) being mechanically linked by means of an upper guide unit (31) of a guide system to the chassis (4) which is configured such that the inclination of both the headrest portion (21) and the backrest portion (23) increase the inclination thereof with respect to the vertical as the frame (2) moves from the neutral position N to the comfort position C thereof.

A motor vehicle includes a seat having a backrest with an adjustable backrest inclination, an interior device, and a controllable device. A touch-sensitive screen for controlling the controllable device is arranged in or on the interior device. The inclination, curvature and/or position of the touch-sensitive screen is adjustable relative to the interior device. A control device in the motor vehicle can control the inclination, curvature and/or the position of the touch-sensitive screen depending on the backrest inclination of the backrest. Therefore, a device in a motor vehicle can be controlled in a more comfortable manner by controlling the inclination, curvature, and/or the position of the device depending on the backrest inclination of the backrest of the seat in the motor vehicle.
