Massage chair shoulder back kneading mechanism

Abstract

The invention discloses a shoulder and back kneading mechanism used in massage chairs, which comprises kneading arms and massaging wheels. The invention is characterized in that the shoulder and back kneading mechanism is also provided with an upper swing arm, a lower swing arm, a swing arm connecting rod and springs. The kneading arm comprises an inner kneading arm and an outer kneading arm which are integrated into a whole through screws; the upper swing arm is movably connected with the lower swing arm; the upper swing arm and the lower swing arm are connected with the kneading arm through crank screws; the swing arm connecting rod is connected with the kneading arm; the springs are respectively connected with the kneading arm and the lower swing arm; the kneading arm, the swing arm connecting rod, the upper swing arm and the lower swing arm form into a linkage mechanism. The depth and distance in vertical direction of the upper massage wheel and the lower massage wheel of the invention can be adapted freely according to the back curve of human body. The massage depth is uniform, therefore, the massage wheels more perfectly simulate massage effects of a real person and cause people feel more comfortable; the springs has buffer effects to massage strength and massage wheel speed, thus making the massage operation be more gentle. Besides, the massage effects are especially suitable for middle-aged and elder people.

Description

technical field [0001] The invention relates to a massage device, in particular to a shoulder and back kneading mechanism used in a massage chair.

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art that the massage range cannot be adjusted, the longitudinal position of the massage wheel cannot be adaptively changed, and the use comfort is poor, and to provide a shoulder pad with a reasonable structure design, a compact and simple structure. Back kneading mechanism, the vertical depth and distance of the upper and lower massage wheels of the shoulder and back kneading mechanism can adapt to the curve of the back and waist of the human body, so that the mechanical massage can more perfectly simulate the human massage technique and make people feel more comfortable
