Description
Technical Field
The utility model relates to a chair seat, in particular to a chair seat with a waist rest.
Background
The chair back of the prior common chair is generally straight up and down or the middle and down of the chair back
The part has slight arch to improve the lumbar support of the seat, but the arch structure has no elasticity, and the waist is hard and uncomfortable when being leaned on the arch; also have the chair that takes the waist to lean on in the market, like the utility model patent of the grant bulletin number CN 209694608U, just disclose a chair with dismantlement formula waist and lean on the structure, the waist is leaned on and is fixed on the back of the chair through the support frame, and the equipment is wasted time and energy, and the waist is leaned on and needs accessories such as support frame, has increased the cost of chair. In addition, the waist rest has a short length, and the contact area with the waist of a human body is too small, so that the support performance and the comfort are affected.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects existing in the prior art, the utility model aims to provide a chair seat with a waist rest, wherein the waist rest and the chair seat are integrally formed without additional assembly, and the chair seat has good elasticity and has the characteristics of low cost and comfort.
In order to realize the purpose, the following technical scheme is adopted:
the chair seat with the waist support comprises a back plate and a seat plate, and is characterized in that: the position that the backplate corresponds human waist is provided with the fretwork slotted hole, the place that the backplate corresponds the fretwork slotted hole is provided with the elasticity backup plate, and elasticity backup plate one end is fixed with the backplate, and the both sides and the other end of elasticity backup plate are unsettled.
The elastic backup plate extends downwards from the upper edge of the hollowed-out slotted hole and arches forwards relative to the back plate; one end of the elastic backup plate is in smooth transition with the back plate at the upper edge of the hollowed-out slotted hole, so that the elastic backup plate has a natural radian according with human engineering.
In the horizontal direction, the two sides of the elastic backup plate protrude forwards, the middle of the elastic backup plate is slightly recessed backwards, and the two sides form butterfly wings to be attached to the waist of a human body.
The hollow slotted hole is rectangular, and the width and the height of the hollow slotted hole are greater than one half of the width and the height of the back plate and less than three fourths of the width and the height of the back plate.
The hollow slotted hole extends from the chair back to the corner of the chair back connected with the chair seat.
The back plate, the seat plate and the elastic backup plate are integrally formed through injection molding.
And reinforcing ribs are arranged on the outer side surfaces of the back plate, the seat plate and the elastic backup plate.
The utility model is provided with the hollowed-out slotted hole on the back plate, and the arched elastic backup plate is arranged at the hollowed-out slotted hole, one end of the elastic backup plate is fixed with the back plate, and other parts are in a suspended state; the above structure can bring the following effects: firstly, the back plate is provided with a hollowed-out slotted hole, and the hollowed-out slotted hole is at least one half larger than the back plate, so that the back plate has elasticity; secondly, the suspended elastic backup plate also has elasticity; when the waist of the human body leans against the elastic backup plate, the double elasticity plays a supporting role, so that people feel very comfortable. The utility model discloses seat support, elasticity backup plate do not need extra equipment through the integrated into one piece that moulds plastics, have not only saved the cost, also can improve the efficiency of production.

Detailed Description
As shown in fig. 1-3, the chair seat with waist rest comprises a back plate 1 and a seat plate 2, wherein a hollowed-out slot hole 3 is formed in the position of the back plate corresponding to the waist of a human body, an elastic back plate 4 is arranged in the position of the back plate corresponding to the hollowed-out slot hole, one end of the elastic back plate is fixed with the back plate, and two sides and the other end of the elastic back plate are suspended.
The elastic backup plate extends downwards from the upper edge of the hollowed-out slotted hole and arches forwards relative to the back plate; one end of the elastic backup plate is in smooth transition with the back plate at the upper edge of the hollowed-out slotted hole, so that the elastic backup plate has a natural radian according with human engineering.
In the horizontal direction, the two sides of the elastic backup plate protrude forwards, the middle of the elastic backup plate is slightly recessed backwards, and the two sides form butterfly wings to be attached to the waist of a human body.
The hollow slotted hole is rectangular, and the width and the height of the hollow slotted hole are greater than one half of the width and the height of the back plate and less than three fourths of the width and the height of the back plate. Because the elastic backup plate is arranged corresponding to the hollow-out slotted hole, the size of the elastic backup plate is equivalent to that of the hollow-out slotted hole, the width and the height of the elastic backup plate are more than one half of the width and the height of the back plate and less than three fourths of the width and the height of the back plate, and the contact area with the waist can be increased due to the size.
The hollow slotted holes extend from the chair back to the connecting corner 5 of the chair back and the chair seat. The corners are hollowed out, so that the overall elasticity can be increased.
The back plate, the seat plate and the elastic backup plate are integrally formed through injection molding.
And reinforcing ribs are arranged on the outer side surfaces of the back plate, the seat plate and the elastic backup plate.
The utility model is provided with the hollowed-out slotted hole on the back plate, and the arched elastic backup plate is arranged at the hollowed-out slotted hole, one end of the elastic backup plate is fixed with the back plate, and other parts are in a suspended state; the above structure can bring the following effects: firstly, the back plate is provided with a hollowed-out slotted hole, and the hollowed-out slotted hole is at least one half larger than the back plate, so that the back plate has elasticity; secondly, the suspended elastic backup plate also has elasticity; when the waist of the human body leans against the elastic backup plate, the double elasticity plays a supporting role, so that people feel very comfortable. The utility model discloses seat support, elasticity backup plate do not need extra equipment through the integrated into one piece that moulds plastics, have not only saved the cost, also can improve the efficiency of production.
