Description

a leisure chair

technical field

The utility model relates to a leisure chair, in particular to a comfortable leisure chair which can adjust the angles of the waist rest and the head rest.

Background technique

Seats are one of the necessary furniture for human life. At present, common leisure chairs are mainly composed of bases, armrests, seat seats, and chair backs. In order to meet the user's reclining needs, the back of some leisure chairs is designed to adjust the inclination angle of the seat back, so that the occupant can adjust the reclining angle of the chair as needed for reclining and resting.

In order to make the occupant more comfortable, some leisure chairs have a protruding lumbar support on the back of the chair corresponding to the occupant's waist position; a headrest is designed corresponding to the occupant's head position. However, the combination angle of the lumbar and headrest and the seat back is generally fixed, and the waist and head can be supported by the lumbar and headrest during riding to enhance the riding comfort.

When the occupant needs to adjust the back of the seat or adjust the recline angle of the back of the seat so as to lie down, the required lumbar or headrest support position also needs to be adjusted accordingly. It is not adjustable, and although the fixed lumbar support and head support can be used to support the waist or head of the human body to improve the comfort of the seat back support when riding, it still feels uncomfortable. In particular, when the angle of the headrest cannot be adjusted corresponding to the reclining of the chair, it is easy to cause the head to recede excessively, resulting in uncomfortable reclining of the head.

Contents of the invention

In view of the above reasons, the purpose of this utility model is to provide a leisure chair with a movable waist and headrest structure, which can adjust the angle of the waist and headrest corresponding to the inclination angle of the chair back. Disassembled, small size, easy to transport and load.

In order to achieve the above purpose, the utility model adopts the following design scheme: a leisure chair, which is mainly composed of a base, an armrest, a seat, a chair back, a waist rest, and a headrest; the armrest is fixedly connected to the base, and the front and rear ends of the armrest They are respectively pivotally connected to the seat and the seat back; the rear end of the seat seat is pivotally connected to the bottom end of the seat back, and the elevation angle of the seat back can be adjusted so that the seat seat can be displaced accordingly; 1. The pivot joint of the headrest combination; the waist rest is composed of a main body, an engaging piece, and a connecting piece. The upper and lower ends of the main body are respectively provided with a propping portion with an appropriate curvature, and the two ends of the main body are fixedly provided with engaging pieces ; The engaging piece is joined with the main body at an appropriate angle, and a convex column and an engaging column that can be pivotally combined with the armrest and the linking piece are protruded on the side; the two ends of the linking piece are provided with pivot holes, and are respectively connected by the pivoting elements It is combined with the joint column of the lumbar support and the seat pivotally; the headrest is composed of a main body and a connecting rod. A pivotal joint that can be combined with the seat back is provided under the main body, and a joint that can be combined with one end of the connecting rod is provided on the inside of the pivotal joint. column; the connecting rod is a strip-shaped rod body, and its two ends are provided with pivot holes to be pivotally connected with the joint post of the main body and the joint post of the lumbar support.

Because the utility model adopts the above structure, the lumbar support and the head support can be moved corresponding to the offset of the chair back, so that when the chair is reclined, the top rest part above the waist rest can be rotated inward, and the bottom rest part The outward rotation offset makes the bottom of the chair back protrude at the junction of the seat to improve the comfort of reclining support. The headrest can be driven inwardly by the linkage plate and the connecting rod, so that the headrest has an appropriate support elevation angle to improve the support of the head. In addition, the utility model can also easily assemble and disassemble the leisure chair by using the connecting piece. When manufactured in the factory, the seat and back of the leisure chair can be disassembled through the connecting piece, so that the seat and back of the chair can be stacked during packaging and transportation, which greatly reduces the volume of transportation and loading, and has better transportation convenience gender and economic efficiency.

Detailed ways

Please refer to Fig. 1 to Fig. 3, the leisure chair of the utility model is made up of base 1, armrest 2, seat 3, chair back 4, waist rest 5, head rest 6. The armrest 2 is fixedly connected to the base 1; its front and rear ends have joints 21 and 22 respectively, and are pivotally connected with the seat 3 and the chair back 4; The chair back 4 is properly tilted so that the seat 3 can be displaced accordingly; the lower and upper sides of the chair back 4 are respectively provided with pivot joints 41 and 42 which can be combined with the waist rest 5 and the head rest 6 .

The lumbar support 5 is composed of a main body 51, an engaging piece 52, and a connecting piece 53; the upper and lower ends of the main body 51 are respectively provided with abutting portions 511, 512 with appropriate curvatures, and the engaging pieces 52 are fixed at both ends; the engaging piece 52 Engage with the main body 51 at an appropriate angle, and protrude from the side with a convex column 521 and an engaging column 522 that can be pivotally combined with the armrest 2 and the linkage piece 53 respectively; the two ends of the linkage piece 53 are provided with pivot holes 531 and 532 , and are respectively pivotally combined with the joint column 522 of the lumbar support 5 and the seat 3 through pivoting elements.

The headrest 6 is composed of a main body 61 and a connecting rod 62. A pivot joint 611 combined with the seat back 4 is provided under the main body 61, and an engaging column 612 for combining with one end of the connecting rod 62 is provided inside the pivot joint 611; the connecting rod 62 is an elongated rod body, and pivot holes 621 and 622 are provided at two ends to pivotally connect with the joint post 612 of the main body 61 and the joint post 522 of the lumbar support 5 respectively.
