In order to increase the comfort of the chair and reduce the damage to the human body caused by long-time sitting, the office chair usually adopts the design of adjustable inclination angle, and the inclination angle of the chair is adjusted according to the requirement. The seat with the angle adjusting device is usually provided with an elastic buffer body filled between the connecting part and the adjusting base, and the inclination angle of the seat is dynamically adjusted according to different stress of the elastic buffer body, so that the seat is more suitable for the stress surface when a person sits on the seat, and 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 7, the seat angle adjusting device comprises an adjusting base 100, a connecting part 200, an elastic buffer body 300 and a limiting protrusion 400; the adjusting base 100 is hollow and has a ring-shaped first inner connecting surface 101, the ring-shaped first inner connecting surface encloses to form a cylindrical cavity, and the adjusting base 100 is used for connecting and supporting a seat surface of a seat; the connecting part 200 is used for connecting a supporting column 500 of a seat and the adjusting base 100, the connecting part 200 is annular 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 supporting column 500; the elastic buffer body 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 protrusion 400 is embedded in the elastic buffer body 300 to reduce the maximum deformation of the elastic buffer body 300.
The adjustment of the seat surface inclination angle adopts 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 buffer 300 as a member for providing elastic restoring force. When the same amount of force is applied, the larger the thickness of the elastic buffer 300, the larger the amount of deformation thereof, the larger the change in the seat surface angle, and the easier the adjustment of the seat surface angle.
In order to realize the difference of the inclination angle adjustment of the seat in different directions, in a specific embodiment, the cylindrical cavity is in an elliptic cylinder shape, the major axis direction of the ellipse is the front-back swing direction of the seat, and the minor axis direction of the ellipse is the left-right swing direction of the seat, so that the effect that the maximum inclination angle of the front-back swing of the seat is larger than the maximum inclination angle of the left-right swing of the seat is achieved.
The seat angle adjusting device provided by the invention is suitable for a seat with a single supporting column, the connecting part 200 is connected with the supporting column 500 of the seat, the adjusting base 100 is connected with the seat surface of the seat, the elastic buffer body 300 is arranged between the rigid adjusting base 100 and the rigid connecting part 200, when the seat surface is stressed by unbalanced top-down force, the seat surface can deflect, and the elastic buffer body 300 can be stressed by lateral pressure due to deflection of the seat surface, so that elastic deformation is generated, and elastic restoring force is generated.
The elastic buffer body 300 is preferably made of rubber and has a thickness of 5mm to 25 mm. After the elastic buffer 300 is subjected to multiple times of deformation recovery, especially multiple times of deformation recovery with large deformation amount, the elastic deformation capability of the elastic buffer becomes weak, so that the elastic buffer can not recover normally after being deformed. In order to prolong the reduction of the elastic deformation capability of the elastic buffering body 300, increase the times of the elastic deformation and prolong the service life of the elastic buffering body, a limiting protrusion 400 arranged along the connecting part 200 or along the circumferential direction of the adjusting base 100 is arranged between the connecting part 200 and the adjusting base 100, the limiting protrusion 400 is embedded in an avoiding position 301 in the elastic buffering body 300, and the avoiding position 301 can be an avoiding hole or an avoiding groove; when the elastic buffering body 300 is deformed laterally, the limiting protrusion 400 can reduce the maximum deformation of the soft elastic buffering body 300 under the condition of ensuring the whole thickness of the elastic buffering body 300, thereby reducing the damage of the elastic buffering body 300 and prolonging the service life of the elastic buffering body. The limiting protrusion 400 may be an annular protrusion or a plurality of tooth-shaped protrusions uniformly arranged in an annular shape.
In other embodiments that employ an annular protrusion, a protrusion height of the annular limiting protrusion in a first direction is smaller than a protrusion height of the annular limiting protrusion in a second direction, wherein the first direction is a front-back swing direction of the seat, and the second direction is a left-right swing direction of the seat. In this embodiment, the limiting effect of the limiting protrusion 400 on the front-back swing of the seat is smaller than the limiting effect on the left-right swing of the seat, so that the maximum inclination angle of the seat in the front-back direction is larger than the maximum inclination angle of the seat in the left-right direction. In other embodiments, the protruding height of the tooth-like protrusions in the first direction is smaller than the protruding height of the tooth-like protrusions in the second direction, or the pitch of the tooth-like protrusions in the first direction is larger than the pitch of the tooth-like protrusions in the second direction.
The places where the elastic buffer body 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 protrusion 400 is disposed at the upper end and/or the lower end of the columnar cavity, and the limiting protrusion 400 is a metal member.
In one embodiment, the limiting protrusion 400 is disposed on the first inner connecting surface 101 of the adjusting base 100, and the protruding height of the limiting protrusion 400 is smaller than the distance between the connecting portion 200 and the adjusting base 100. The circumferentially arranged stopper protrusions 400 are inserted from the outer side surface of the elastic buffer body 300.
In another embodiment, the limiting protrusion 400 is disposed on the outer connecting surface 202 of the connecting portion 200, and the protruding height of the limiting protrusion 400 is smaller than the distance between the connecting portion 200 and the adjusting base 100. The circumferentially arranged limit protrusions 400 are embedded from the inner side surface of the elastic buffer body 300.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
