Description

Seat cushion with sitting posture correcting function

Technical Field

The utility model belongs to the field of seat furniture, concretely relates to seatpad with position of sitting corrects function.

Background

The chair is a furniture widely used in daily families and office places, and is used for people to rest, lie and sit and work. At present, the types of seats are various, but the seats generally have seat surfaces and chair legs, which are the simplest chairs, and the addition of the chair back enables the chair to have a backrest function, so that the back of a person can be supported, and the muscle fatigue of the back of the person during long-time office sitting is relieved.

Most office chairs all have chair backs, seat, chair foot structure now, and in order to alleviate the back fatigue of sitting for a long time, still be equipped with the bulge structure towards the waist on the back of the chair of some chairs for counterbalance with the waist when people's back, accord with the natural curve of people's health, alleviate fatigue. However, such chairs only support the waist when a person sits in a posture as standard as possible, which requires that the person's buttocks lean against the chair back as much as possible and the back sits upright; the practical situation is that most people sit and will have the buttock forward, present a lazy position of sitting, the waist is unsettled this moment, arouses fatigue more easily, has aroused the psoas injury even for a long time.

In a previous patent application, the applicant provided a seat cushion with rollers, all of which could be rolled in one direction, e.g. could be arranged to roll only backwards and not forwards, thus avoiding or slowing down the forward movement of the buttocks and allowing a correct sitting position. However, the applicant finds that the rolling direction is excessively limited by the rolling shaft in the seat cushion of the structure during use, and the sitting person is hard to adjust the sitting posture independently, for example, the resistance is large and troublesome when the sitting person moves forwards because the rolling shaft cannot roll forwards.

Therefore, in view of the above problems, the applicant has made further design and improvement of a seat cushion having a roller structure.

SUMMERY OF THE UTILITY MODEL

To not enough among the above prior art, the utility model provides a seatpad with function is corrected to position of sitting can directly place on the seat, convenient to use, and the unsettled position of sitting of waist forward of adjustment buttock that can be fine makes people's back straight, can effectively alleviate and sit produced tired sense for a long time, and the position of sitting adjustment flexibility is high simultaneously.

In order to solve the above technical problem, the present invention solves the above technical problems.

The seat cushion with the sitting posture correction function comprises side plates which are symmetrically arranged, wherein a plurality of rotatable rolling shafts are arranged between the side plates, each rolling shaft comprises a free rolling shaft capable of rotating forwards and backwards and an unidirectional rolling shaft only capable of rotating unidirectionally, and the unidirectional rolling shafts are arranged at the front end of the seat cushion.

The seatpad simple structure among the prior art generally only plays springiness cushioning's effect, has rotatable roller bearing on the seatpad in this application, and when the people sat, the buttock was arranged in on this roller bearing, under the normal condition, the position of sitting was upright, when the lazy time that looses of people's position of sitting, the buttock had the trend of moving forward, because the one-way roller bearing of seatpad front end can only unidirectional rotation (backward rotation) this moment, consequently can avoid or slow down the buttock and move forward, made people's position of sitting upright.

In a preferred embodiment, two ends of the free roller are arranged on the side plates through two-way bearings, and two ends of the one-way roller are arranged in the side plates through one-way bearings, so that the assembly structure is simple, and the firmness is high.

In a preferred embodiment, 1-3 rollers on the front portion of the seat cushion are one-way rollers for generating resistance to reverse movement.

In a preferred embodiment, a plurality of roller shafts between the side plates are arranged in parallel, and a gap is reserved between adjacent roller shafts, so that the roller shafts can rotate smoothly.

In a preferred embodiment, the bottoms of the two side plates are connected through a bottom plate, a gap is reserved between the bottom plate and the roller, so that the whole structure is stable, and meanwhile, the bottom of the roller is prevented from contacting other objects when in use, so that the rotation is smooth.

In a preferred embodiment, the surface of the roller is covered with a flexible layer, which can be a cloth layer, a sponge layer and the like, so that the comfort level is improved.

In a preferred embodiment, the thickness of the seat cushion close to the front end of the seat cushion is larger than the thickness of the seat cushion close to the rear end of the seat cushion, in this application, the front end refers to the end facing the front of a person in use, the height setting comfort in the structure is high, and the self-conscious sitting posture of the person can be changed to be correct. Meanwhile, the seat cushion is high in front and low in back, and after a person sits on the seat cushion, the buttocks automatically roll backwards under the action of gravity, so that the waist can be automatically attached to the back of the chair, and a good sitting posture is guaranteed.

In a preferred embodiment, a protective pad is arranged on the periphery of the side plate, and the protective pad is generally of a flexible structure, so that the comfort level in use is increased.

Compared with the prior art, the utility model discloses following beneficial effect has: a seat cushion with a sitting posture correcting function can be directly placed on a seat, is convenient to use, can well adjust the sitting posture that the hip is suspended in the air forwards, so that the back of a person is upright, the fatigue caused by sitting for a long time can be effectively relieved, and meanwhile, the sitting posture adjusting flexibility is high.
