Multi-seat chair with cushion capable of changing angle of inclination through power generation of back

Abstract

The invention relates to the technical field of sofas, and discloses a multi-seat chair with cushion capable of changing an angle of inclination through power generation of the back. The multi-seat chair comprises support legs, wherein the upper parts of the support legs are fixedly connected with a lower plate; the upper part of the lower plate is movably connected with a backrest; when a user sits on the upper part of the lower plate, a foot pad inside the support legs is pulled out to relax legs; when the backrest needs to be inclined, power is continuously generated by the back, right-angle springs are extruded, the backrest is inclined downwards, the back of a limiting rod moves together, the backrest is in touch with a push rod, the push rod moves forwards, a connecting rod moves rightwards synchronously, a connecting block moves rightwards, a sliding groove is formed in the surface of the connecting block, a spring is extruded, the sliding groove moves rightwards synchronously,a circular rod moves to the right end of the sliding groove, the angle of a hook changes, the hook is movably connected with the limiting rod for mutual limiting, the angle of inclination of the backrest cannot change, and when the backrest needs to be recovered at an original position, the chair can be recovered to the initial position just by applying slightly larger pressure onto the backrest again.

Description

technical field [0001] The invention relates to the technical field of sofas, in particular to a cushioned multi-seat chair whose back exerts force to change the inclination angle. Background technique [0002] Sofa is one of the common furniture items, also known as chairs. It is generally made into different shapes for different groups of people and different purposes. However, the function of a single chair is relatively monotonous and cannot meet the needs of different groups of people. It is also particularly important that chairs can meet different needs in different occasions. [0003] At present, the existing multi-seat chairs with upholstery generally include a simple seat cushion and a back resting area, and are generally distributed at right angles. When resting, it is generally necessary to change the inclination angle of the chair to increase the comfort, and the recliners made in the current market are generally wooden, because the wooden material is relativel...

[0002] Sofa is one of the common furniture items, also known as chairs. It is generally made into different shapes for different groups of people and different purposes. However, the function of a single chair is relatively monotonous and cannot meet the needs of different groups of people. It is also very important that chairs can meet different needs in different occasions

[0003] At present, the existing multi-seat chairs with upholstery generally include a simple seat cushion and a back resting area, and are generally distributed at right angles. When resting, it is generally necessary to change the inclination angle of the chair to increase the comfort, and the recliners made in the current market are generally wooden, because the wooden material is relatively hard, so the comfort will be reduced when resting, and the current market invented When adjusting the angle of the reclining chair, it is generally necessary to manually adjust the two sides of the entire chair, and it needs to consume a lot of physical strength. For some special groups, it is impossible to use the hands to operate, or those with weak hands cannot operate, so will cause inconvenience to users
