Detailed Description

Reference numerals in the drawings of the specification include: seat frame 1, second clamp plate 2, cushion frame 3, support frame 4, buffer tube 5, return spring 6, first pivot support 7, second pivot support 8, pivot 9, first clamp plate 10.

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Examples

As shown in fig. 1 to 4, the present embodiment provides a cushion adaptive adjustment structure, including cushion frame 3, all be fixed with the supporting part on cushion frame 3 both sides side, the supporting part includes support frame 4, support frame 4 upwards fixes on cushion frame 3, constitutes isosceles trapezoid shape between support frame 4 and the cushion frame 3, and support frame 4 inclines towards the cushion frame 3 outside to the human body sits down. Support frame 4 is gone up the top cover and is equipped with buffer tube 5, and buffer tube 5 coats and is stamped the top board, the top board includes integrated into one piece's first clamp plate 10 and second clamp plate 2, it is greater than 90 "V" style of calligraphy to present the angle between first clamp plate 10 and the second clamp plate 2, the most advanced rotation of top board is connected on the cushion frame, make the second clamp plate 2 of top board be located support frame 4, the first clamp plate 10 of top board is violently put in cushion frame 3, and the equal certain radian of buckling downwards in top board both ends, make the top board both ends more comfortable when contacting with the human body. Be provided with below the top board middle part and be used for the top board to control pivoted runner assembly, runner assembly includes two first pivot supports 7, and two first pivot supports 7 are all fixed on cushion frame 3, and rotate between two first pivot supports 7 and be connected with pivot 9, and pivot 9 both ends all are fixed with second pivot support 8, and second pivot support 8 is fixed with the top board.

Be connected with canceling release mechanical system between cushion frame 3 and the top board, canceling release mechanical system chooses return spring 6 for use in the embodiment, and 6 tops of return spring are fixed with the top board, and 6 bottoms of return spring are fixed with cushion frame 3, and the extension spring is chooseed for use to return spring 6.

During concrete implementation, the seat structure in the scheme can be installed on the seat framework 1, and the V-shaped angle on the upper pressing plate can be designed as required. In a normal state, the second pressing plate 2 of the upper pressing plate is abutted against the supporting frame 4 under the action of the pulling force of the return spring 6, and the first pressing plate 10 of the upper pressing plate is tilted upwards by a certain height.
