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 invention provides a seat angle adjusting device and a seat using the same, wherein referring to fig. 1 to 9, the seat angle adjusting device comprises a base 100, a connecting part 200, an elastic rubber pad 300 and a limiting mechanism 400; the base 100 is hollow and has a ring-shaped first inner connecting surface 101, and the base 100 is used for connecting and supporting a seat surface of a seat; the connecting part 200 is used for connecting a pillar 500 of a seat with the base 100, the connecting part 200 is ring-shaped and has a second inner connecting surface 201 and an outer connecting surface 202, and the second inner connecting surface 201 is used for connecting the pillar 500; the elastic rubber pad 300 is annular and is fittingly embedded between the first inner connecting surface 101 and the outer connecting surface 202 with the first inner connecting surface 101 and the outer connecting surface 202; the limiting mechanism 400 is embedded in the elastic rubber mat 300 to reduce the maximum deformation of the elastic rubber mat 300.
The adjustment of the inclination angle of the seat surface is suitable for adopting a dynamic adjustment mode and needs to have an elastic recovery function. The seat angle adjusting apparatus provided by the present invention employs the elastic rubber pad 300 as a member for providing elastic restoring force. When the same amount of force is applied, the greater the thickness of the elastic rubber pad 300, the greater the amount of deformation thereof, the greater the change in the angle of the seat surface, and the easier the adjustment of the angle of the seat surface.
The seat angle adjusting device provided by the invention is suitable for a single-pillar 500 seat, the connecting part 200 is connected with the pillar 500 of the seat, the base 100 is connected with the seat surface of the seat, the elastic rubber pad 300 is arranged between the rigid base 100 and the rigid connecting part 200, when the seat surface is stressed by unbalanced top-to-bottom force, the seat surface can deflect, and the elastic rubber pad 300 can be stressed by lateral pressure due to the deflection of the seat surface, so that elastic deformation is generated, and elastic restoring force is generated.
The elastic rubber pad 300 is preferably made of rubber and has a thickness of 5mm to 25 mm. After the elastic rubber mat 300 is deformed and restored for many times, especially after being deformed and restored for many times with a large deformation amount, the elastic deformation capability thereof becomes weak, so that the elastic rubber mat cannot be normally restored after being deformed. In order to delay the reduction of the elastic deformation capability of the elastic rubber cushion 300, increase the times of the elastic deformation and prolong the service life of the elastic rubber cushion, the limiting mechanism 400 is arranged in the elastic rubber cushion 300, the limiting mechanism 400 is embedded in the elastic rubber cushion 300, and when the elastic rubber cushion 300 deforms laterally, the limiting mechanism 400 can reduce the maximum deformation of the elastic rubber cushion 300 under the condition of ensuring the thickness of the elastic rubber cushion 300, so that the damage to the elastic rubber cushion 300 is reduced, and the service life of the elastic rubber cushion is prolonged.
The places where the elastic rubber mat 300 has the largest deformation amount when the seat surface angle changes are the upper end and the lower end, therefore, in the present invention, the limiting mechanism 400 is disposed on the upper portion or the lower portion of the elastic rubber mat 300, and the limiting mechanism 400 is a metal member.
In one embodiment, the limiting mechanism 400 is circular, and the normal direction of the limiting mechanism 400 is parallel to the normal direction of the elastic rubber pad 300. The annular limiting mechanism 400 may be embedded in the inner side surface, the outer side surface or the inside of the elastic rubber mat 300. When the limiting mechanism 400 is embedded in the inner side surface or the outer side surface of the elastic rubber mat 300, the inner side surface or the outer side surface of the elastic rubber mat 300 is provided with a corresponding groove 301, and when the limiting mechanism 400 is arranged in the elastic rubber mat 300, the limiting mechanism 400 and the elastic rubber mat 300 are integrally formed. In other embodiments, the limiting mechanism 400 may further include a plurality of mutually independent limiting blocks, and the limiting blocks are equally and uniformly distributed on the elastic rubber mat 300, so that the limiting functions of the limiting mechanism 400 on the seat surface in all directions are the same.
The limiting function of the limiting mechanism 400 on all directions of the seat does not always need to be the same, in another preferred embodiment, as shown in fig. 10, the limiting mechanism 400 comprises a plurality of dentations which are divided into four areas, namely a front area, a rear area, a left area and a right area, wherein the protruding height d of the dentations in the front area and the rear area is1Less than the protruding height d of the dentate projections in the left and right regions2In the present embodiment, the maximum inclination angle of the seat in the front-rear direction is greater than the maximum inclination angle in the left-right direction, and the seat surface is more easily inclined in the front-rear direction. In order to achieve the same object, the present invention provides another embodiment, wherein the pitch of the protrusions in the adjacent front and rear regions is larger than the pitch of the protrusions in the adjacent left and right regions.
In addition, the limiting mechanism 400 may also be disposed on the upper end surface or the lower end surface of the elastic rubber mat 300, and correspondingly, an annular groove 302 for the limiting mechanism 400 to be embedded is disposed on the upper end surface or the lower end surface of the elastic rubber mat 300.
