Sliding pad translation structure at front end of seat cushion

Technical Field

The utility model relates to a sliding pad translation structure of cushion front end, concretely relates to slidable adjustment cushion front end length, sliding pad translation structure that the different sizes of cooperation were taken.

Background

It is known that people who work in offices for a long time often suffer from soreness of the shoulders, the neck, the waist, the back (lower back) and other body parts due to long-term office work on a chair, and even serious people may cause pathological changes of body joints or muscles, so that the inventor pushes out an adjustable chair structure according to an ergonomic design to provide people who fit different body sizes to sit on the chair, so that people can sit on the chair comfortably and relaxedly, and the burden of the body is reduced.

However, in the conventional adjustable seat, the adjustment structure mainly adjusts the height of the seat and the tilt angle of the seat back, and the length and area of the seat cushion of the seat are fixed, so that if the person sitting on the seat is delicate, the sitting posture of the seat is limited by the length of the thigh of the seat, for example, the seat cannot lean against the seat back when sitting upright, and a comfortable sitting posture cannot be provided for the seat; when the person who takes the seat is tall and big, the seat cushion of the seat is small in length, only the buttocks and partial thighs of the person can be seated on the seat cushion, and the person cannot comfortably and loosely take the seat, so that the conventional adjustable seat can only comfortably take the person with a single or similar body type, and cannot provide the same comfortable taking effect for the persons with different body types.

Therefore, how to provide a device or structure that can effectively adjust the length of the seat cushion in accordance with the thigh lengths of various body types so that people of different body types can comfortably take the seat cushion is the direction in which the inventors of the present invention are eagerly interested to research and improve.

Therefore, in view of the above-mentioned shortcomings, the inventor of the present invention has devised the above-mentioned utility model patent by collecting relevant data, evaluating and considering in many ways, and continuously trying and modifying with years of experience accumulated in the industry.
