A tilt structure allows the tilt of a console to be changed through simple motion and has a simple configuration. The tilt structure includes: a second frame attached to an upper portion of a first frame and is swingable upward and downward; and a control member attached to the second frame and is tiltable backward and forward through a tilting shaft. The control member includes a guide part with a groove housing a first frame pin. A locked and unlocked state switch to each other by causing the control member to tilt. The locked state includes a pin engaged with any of the engagement parts. The unlocked state includes the pin disengaged. The tilt of the second frame relative to the first frame is changed by engaging the pin with an arbitrary engagement part of any of the engagement parts and changing a distance between the tilting shaft and pin.

Tilt structure for console and console

A tilt structure to be provided allows the tilt of a console to be changed through simple motion and has a simple configuration. A control memberis coupled to a second frameat a first coupling position Pand is coupled to a first frameat a second coupling position Pprovided below the first coupling position P. Controlling the control membermakes the height of the first coupling position Padjustable. The tilt of the second frameis changed in response to the height of the first coupling position P

Tilt structure for console

A tilt structure to be provided allows the tilt of a console to be changed through simple motion and has a simple configuration. A link mechanism (a mechanism similar to a slider crank mechanism) composed of three turning pairs and one sliding pair is formed using a first framea second framea sliderand a connection memberThe tilt structure includes a control memberorfor fixing or unfixing the tilt of the second frameThe control memberoris provided controllably in order to lock or unlock motion of the link mechanism.

An armrest structure for seat includes an armrest configured to move in a lateral width direction of the seat, a guide block configured to move in a front-rear direction of the seat, and an operation portion configured to be manually operated, such that the guide block moves in the front-rear direction. The armrest and the guide block are slidably engaged with each other in a direction inclined with respect to the lateral width direction and the front-rear direction of the seat. The armrest is configured to move in conjunction with the guide block in the lateral width direction, in response to an operation that the operation portion is operated to move the guide block in the front-rear direction. According to this armrest structure, an interval between the armrest on both sides can be adjusted in accordance with the physique and the posture of a seated person.
