Back support structure and seat

The present invention is a back support structure and a seat, especially a back support structure and a seat having a curved function according to a user's back curve.

The seat on the market generally includes a seat support leg, a seat cushion and a seat back, wherein the seat cushion is disposed on the seat support leg, and the seat back is disposed on the seat On the back side of the seat cushion, when the user rides the seat, the seat is usually seated on the seat cushion and rests against the seat back for rest. However, in the prior art seat, the seat back is usually a whole The structure of the block body can not be deformed according to the user of different body types, so the seat back has poor support effect on the back of the user, and does not conform to the design concept of ergonomics, so that the user will have a seat when riding The feeling of poor comfort.

In addition, there is a certain hollow position between the seat back and the seat cushion. For users who sit on the seat cushion for a long time and rest on the seat back, it will not only affect the user's comfort, but also use it. The spine of the waist causes an influence.

In addition, the upper and lower portions of the seat back frame are generally flush, so that when the user stretches the arm outward, it is easily interfered by the upper portion of the seat back, which also affects the comfort of the user using the seat.

The main purpose of this creation is to provide a back support structure and a seat to improve the comfort of today's seats to provide users with poor ride comfort.

In order to achieve the purpose of the prior disclosure, the back support structure of the present invention comprises: a strip-shaped curved strip which is elastically bendable, and an upper connecting portion and a lower connecting portion are respectively arranged at upper and lower opposite ends; and a plurality of supporting strips are respectively The support strips are respectively disposed on the front side of the curved strips, and each of the support strips comprises a support portion, and two sides of the support unit respectively form a support portion, and respectively protrude outwardly from the two sides of the curved strip.

The back support structure of the present invention is installed on the seat and provides support for the back waist of the user when riding the seat. The curved strip can be bent to adapt to the curvature curve of the user, and is supported by the support strips. The support supports the back of the user to improve the comfort of the user when riding on the seat, thereby providing a comfortable support structure for the user to rest.

Wherein, the front side of the curved strip is spaced apart from the plurality of inner grooves, and the curved strip is provided with a plurality of outer grooves at the rear side, and the inner grooves and the outer grooves are staggered from top to bottom. Arranging, further, the inner groove and the inner portion of the outer groove are further selectively respectively filled with a corresponding spacer, and the curved strip is filled by the spacers filled in the inner groove and the outer groove The strength of the elastic deformation, while avoiding plastic deformation of the curved strip.

In addition, the front side of the supporting unit forms an arcuate concave surface which is recessed backward, and each supporting strip may further comprise a sponge layer covering the front side of the corresponding supporting unit when the user is in the ride. When the seat is placed on the seat, the user's back ridges will lean against the support bars, so that the support portions of the support bars further provide the user's massage effect during the process of expanding and contracting under the user's leaning, and the sponge is provided. The layer can prevent the support unit from directly pressing the back of the user and provide a soft touch to the user, thereby improving the comfort of use of the back support structure.

In order to achieve the foregoing, the seat provided by the present invention comprises the aforementioned back support structure, the seat has a seat cushion and a seat back frame, and the seat back frame is disposed on the rear side of the seat cushion The seat back frame can be divided into a headrest portion and a backrest portion from top to bottom, a hollow space is formed in the backrest portion, and a lifting structure is disposed at the bottom of the backrest portion, and the back waist support structure is located The upper connecting portion is disposed at a hollow space of the seat back frame, and the upper connecting portion is disposed at a joint of the headrest portion and the backrest portion of the seat back frame, and the lower connecting portion is disposed on the lifting structure.

When the user is riding the seat, the seat can provide support for the back waist when the user rides the seat through the back waist support structure, thereby improving the comfort of the user when riding the seat, and further Adjusting the height position of the bottom of the curved strip to adjust the support force provided by the back waist support structure when the user leans on can meet the support force adjustment requirements provided by different users for the back waist support structure.

In addition, a lumbar support plate is pivotally disposed on a top surface of the seat cushion near the seat back, and the lumbar support plate pivotally swings and abuts against a front side of the back support structure, the seat back frame The width of the headrest portion is smaller than the width of the backrest portion, and a notch is formed on each of the two sides of the headrest portion, the waist support plate can support the back waist of the user, and the upper side of the seat back frame The gap allows the user's arm to swing freely without interference, which further enhances the ride comfort of the seat.
