According to the aviation passenger seat dining table with the rapid locking mechanism, the dining table can be used or stored through one motion, meanwhile, a non-protrudinglocking mechanism is integrated, and head collision damage caused to passengers on the back row can be avoided.

Description

technical field [0001] The invention relates to the technical field of aviation seat dining tables, in particular to an airline passenger seat dining table with a quick locking mechanism. Background technique [0002] At present, the locking of the known air passenger seat dining table is realized by pressing the lock bolt protruding from the dining table surface against the dining table surface. When the passenger uses the dining table, the lock bolt needs to be rotated away from the surface of the dining table, so that the table can be used; of the lock. [0003] However, this structure has the following problems: [0004] 1. The lock bolt (knob) protrudes from the backrest dining table. During emergency evacuation, it is easy for passengers to rub the lock bolt (knob) so that the dining table is unlocked and unfolded, affecting emergency evacuation and easily causing non-compliance with airworthiness requirements; [0005] 2. In the HIC test, the exposed lock (knob) is...

AI Technical Summary

Problems solved by technology

[0004] 1. The lock bolt (knob) protrudes from the backrest dining table. During emergency evacuation, it is easy for passengers to rub the lock bolt (knob) so that the dining table is unlocked and unfolded, affecting emergency evacuation and easily causing non-compliance with airworthiness requirements;

[0005] 2. In the HIC test, the exposed lock (knob) is very easy to be broken by the head of the test dummy, or flipped, and the lower part of the lock (knob) is tilted, causing the dining table to fall out or unfold directly, affecting emergency evacuation requirements;

[0006] 3. It is easy to cause fatal impact injury

The lock bolt (knob) protrudes from the surface of the backrest, and when it is hit by the head of the test dummy, it is easy to cause blunt impact injury;

[0007] 4. The rotary lock (knob) is not convenient enough for the operation of using the dining table and collecting the dining table

This makes it impossible for passengers to push and lock the dining table in a panic when the dining table is unfolded in an emergency evacuation situation.
