Technical Field

[0001] The invention belongs to the technical field of automobile seats, and in particular relates to a front end lifting structure of an automobile seat. Background Art

[0002] With the development of automobile technology, people's requirements for seat comfort are getting higher and higher. In order to improve riding comfort, the structure and function of automobile seats are constantly improved. The seat posture is determined by the seat frame structure. The seat posture includes the seat back angle, leg support extension length and angle, seat frame height and angle, etc. It is one of the main factors affecting seat comfort.

[0003] During driving, the goal of seat posture adjustment is to meet the comfort requirements of the three main parts of the passenger's legs, feet and torso, so that all parts of the passenger's body are in a highly relaxed state. At present, conventional seat angle adjustment usually only considers the angle adjustment of the seat back to improve the comfort of the passenger's waist and back, but does not consider the comfort of the hips and legs.

[0004] Therefore, it is necessary to design a front end lifting mechanism for a car seat to adjust the angle of the car seat pan by electric / manual means to better meet the riding comfort of passengers. Summary of the invention

[0005] The present invention provides a front end lifting structure of a car seat, which can solve the problems existing in the prior art and improve the riding comfort of passengers.
