Abstract

An automatic double helix turning and setting device of side row stand seat comprises a frame, a turning and setting main axis arranged on the frame and fixed to the corner of the seat, and a helix side transmission mechanism arranged on the frame. The helix side transmission mechanism comprises a chute arranged in parallel with the main axis, a nut slider emboitemented in the chute, and a silk pole screw thread fitted with the nut slider and connected with the driving motor. A blade is arranged on the main axis and is helical in predetermined angle. An upper and lower turning and setting bearing sleeve is arranged on the nut slider and can wavily cling on the blade. The invention provides an automatic double helix turning and setting device of side row stand seat with the advantages of simple structure, high transmission accuracy, and low failure rate.

Description

(1) Technical field [0001] The invention relates to an automatic turning and folding seat, in particular to an automatic turning and turning device for a whole row of stands seats. (2) Background technology [0002] Existing automatic seat turning device, such as the Chinese invention patent application with patent application number CN00116466. The middle part of a swivel foot is fixed on the rotating shaft located at the front upper part of the base, its upper end is fixed with the seat, a step is arranged at the lower end, and another rotating shaft is arranged at the rear lower part of the base, corresponding to the rotating shaft. A support arm is fixed on the position of the pin, and when the seat was turned up and positioned, the free end of the support arm just abuts against the step at the lower end of the pivoting foot. [0003] Another example is the Chinese Utility Model Patent of Patent No. CN03231310.1, which discloses an electric flipping positioning device f...
