Technical Field
The invention belongs to the technical field of helicopter seats, and particularly relates to a helicopter seat backrest adjusting mechanism with a guide groove.
Background
With the continuous improvement of helicopter technology, the requirements for man-machine efficiency are also becoming more and more stringent. As a key product necessary and commonly used by a driver, a seat receives more and more attention in recent years on multiple man-machine efficacy indexes such as comfort, durability, stroke adjustment and the like. In particular, the adjustment travel and the adjustment mode of the pilot's seat, directly affect the pilot's operational and visual accessibility to all the devices in the cockpit. In addition, the comfortable waist curve arc lines required by drivers in different human percentiles are different, and the requirements on the elevation angle of the seat backrest are different. Therefore, there is a need for a convenient and reliable seat adjustment mechanism that meets the pilot's varying needs for the angle of the seat back.
At present, the common backrest adjusting scheme is that the backrest is lowered and folded through mechanisms such as a lock or a gear, and the backrest adjusting requirement is met. However, for helicopter operators, merely adjusting the seat back will result in an increase in the body opening angle at the driver's hip. Research shows that with the increase of the body opening angle, the impact resistance of the human body can be obviously reduced, which is not beneficial to ensuring the flight safety. To sum up, if a seat backrest adjusting mechanism can be obtained, the requirements of backrest angle adjustment and body opening angle control without increase can be met simultaneously, and the seat backrest adjusting mechanism has obvious significance for improving the crash resistance of a helicopter seat and ensuring the safety of a driver.

The bayonet connector 705 and the bearing shaft group 706 are fixed with the bayonet 403, and the force borne by the bayonet 403 is transferred to the whole handle assembly 107, thereby being transferred to the bearing rod 102.
The opening angle of the L-shaped chair basin 109 is controlled to be 100-110 degrees, and the lower ends of the two sides of the L-shaped chair basin are provided with grooves with the same molded surfaces as the guide grooves on the guide sheets 302 in the guide assembly 103, so that the seat does not interfere when moving around the rotating shaft 101, and force transmission is reliable and smooth.
In use, an occupant sits in the seat and presses adjustment button 702 on handle assembly 107 to push latch 705 rearwardly through long button 707 to disengage it from latch tab 105. At this time, the passenger presses the L-shaped seat pan 109 backward to rotate around the rotating shaft 101, and at the same time, the guide block 303 is moved along the inner groove of the guide piece 302. After the chair is adjusted to a proper position, the adjusting button 702 is loosened, the bayonet 705 is locked with the bayonet plate 105, and the stress and the moment of the chair are sequentially transmitted to the handle assembly 107, the bearing rod 102, the guide block 303 and the locking ring 301 through the locking position and finally transmitted to the chair leg support 108 to be dispersed on the floor.
According to the technical scheme, the force transmission mechanism is formed by the rotating shaft, the bearing rod and other parts, so that when the inclination angle of the seat is adjusted, the opening angle of the seat back and the seat surface is unchanged, and the safety of passengers is guaranteed; the stress and the moment of the seat are transmitted on the basis of ensuring the requirement of the backrest rotation adjustment through the guide assembly; the optimized locking plate meets the pitching adjustment requirements of the passengers at various angles; compared with the traditional mechanism that each subsystem performs action control through independent parts, the mechanism has higher integration level and fewer parts, and is convenient to maintain and repair.
