Kind Code:
A1
Abstract:
A dummy for a sitting posture pressure comfort test, comprising: a head (1), upper arms (2), lower arms (3), a torso (4), upper legs (5), lower legs (6), hip joints, knee joints, shoulder joints and elbow joints. The head (1) is fixedly connected to the torso (4). The torso (4) is connected to the upper legs (5) by means of the hip joints. The upper legs (5) are connected to the lower legs (6) by means of the knee joints. The upper arms (2) are connected to the lower arms (3) by means of the elbow joints. The head (1), the upper arms (2), the lower arms (3), the torso (4), each upper leg (5) and lower leg (6) comprises, from the outside to the inside, an epidermal layer (8), a support layer (9) and an inner layer (10). The torso (4) and the upper legs (5) are each provided with a plurality of pressure sensors. A first center-of-gravity adjustment mechanism is provided inside the torso (4). The head (1), the upper arms (2), the lower arms (3), the upper legs (5) and the lower legs (6) are internally provided with a second center-of-gravity adjustment mechanism. The present dummy may be used as a standard test tool for comfort testing of a seat product, is capable of calculating seat structure size parameters and human body posture parameters of a comfortable sitting posture, and is capable of measuring structural ergonomics and human-machine interaction pressure parameters such as seat surface height, depth, hardness and body pressure distribution of a comfortable sitting posture.
