In order to increase the comfort of the chair and reduce the injury to human body caused by long-time sitting, the office chair usually adopts a height-adjustable design, and the height of the chair is adjusted and fixed according to the requirement. The seat with the backrest usually adopts the backrest with an elastic return device, and the inclination angle of the backrest is dynamically adjusted according to different stresses. The seat surface of the seat is usually in a fixed angle, and the seat surface is not adjustable in a horizontal plane, but in some cases, the angle of the seat surface also needs to be dynamically adjusted to better fit the stress surface when a person sits on the seat, so that the comfort of the seat is improved.
The utility model provides a seat angle adjusting device and a seat adopting the same, wherein the seat angle adjusting device is used for adjusting the inclination angle of a seat surface, and particularly comprises a base 100, a connecting part 200 and an elastic rubber cushion 300; the base 100 is used for connecting and supporting a seat surface of a seat, and the base 100 has a first inner connecting surface 101 in a ring shape; the connecting part 200 is used for connecting the pillar 400 of the seat and the base 100; the connecting portion 200 is ring-shaped and has a second inner connecting surface 201 and an outer connecting surface 202, the second inner connecting surface 201 is used for connecting the pillar 400; the second inner connecting surface 201 is a cylindrical surface, and the first inner connecting surface 101 is disposed in a manner of tapering from the middle portion to the top portion of the first inner connecting surface 101 in the height direction of the seat; the elastic rubber pad 300 is annular and is embedded between the first inner connecting surface 101 and the outer connecting surface 202 in a manner of being matched with the first inner connecting surface 101 and the outer connecting surface 202.
