Abstract
A seat for mobility is configured for a seating direction of the seat to be changed, such that the convenience of use of the seat may be ensured, the weight and volume may be reduced by structural simplification, and the manufacturing costs may be reduced.
Claims14
A seat for mobility, the seat comprising:
- guide rails provided on a floor surface of the mobility;
- support portions movably mounted on the guide rails;
- link portions rotatably connected to the support portions and including first connection portions and second connection portions spaced apart from a rotation center;
- a back frame tiltably mounted on the support portions and including first operation portions to which the first connection portions of the link portions are rotatably engaged;
- and
- a cushion frame rotatably mounted on the support portions and including second operation portions to which the second connection portions of the link portions are rotatably engaged, the cushion frame being configured to be rotated by the link portions in conjunction with a tilting operation of the back frame,
- wherein the first connection portions are spaced from the rotation center by a first predetermined distance and the second connection portions are spaced from the rotation center by a second predetermined distance, and
- wherein the second predetermined distance is longer than the first predetermined distance.

A seat for mobility, the seat comprising:
- guide rails provided on a floor surface of the mobility;
- support portions movably mounted on the guide rails;
- link portions rotatably connected to the support portions and including first connection portions and second connection portions spaced apart from a rotation center;
- a back frame tiltably mounted on the support portions and including first operation portions to which the first connection portions of the link portions are rotatably engaged;
- and
- a cushion frame rotatably mounted on the support portions and including second operation portions to which the second connection portions of the link portions are rotatably engaged, the cushion frame being configured to be rotated by the link portions in conjunction with a tilting operation of the back frame,
- wherein the first connection portions and the second connection portions are configured as protrusions, the first operation portions and the second operation portions are configured as slits, and the protrusions and the slits define insertion structures, and
- wherein in the slits related the first operation portions, and the second operation portions, in a state in which the back frame and the cushion frame are rotated on lines perpendicular to an upward/downward direction, the protrusions of the first connection portions are positioned at uppermost end portions of the slits, and the protrusions of the second connection portions and the second operation portions are positioned at lowermost end portions of the slits.

- guide rails provided on a floor surface of the mobility;
- support portions movably mounted on the guide rails;
- link portions rotatably connected to the support portions and including first connection portions and second connection portions spaced apart from a rotation center;
- a back frame tiltably mounted on the support portions and including first operation portions to which the first connection portions of the link portions are rotatably engaged;
- and
- a cushion frame rotatably mounted on the support portions and including second operation portions to which the second connection portions of the link portions are rotatably engaged, the cushion frame being configured to be rotated by the link portions in conjunction with a tilting operation of the back frame,
- wherein the first connection portions and the second connection portions are configured as protrusions, the first operation portions and the second operation portions are configured as slits, and the protrusions and the slits define insertion structures, and
- wherein a first end portion of the link portions is rotatably mounted on the support portions, the first connection portions and the second connection portions are sequentially spaced apart from each other toward a second end portion opposite to the first end portion, a length of the slit of each of the first operation portions are shorter than a length of the slit of each of the second operation portions so that a rotation amount of the cushion frame is greater than a tilting amount of the back frame.
