Problems solved by technology

However, this stiffness can cause damage to the occupants' vital internal organs and spine as little energy is dampened or absorbed during an accident
Conversely, if the leg assembly is too soft, excessive deformation or failure will occur in a crash

Embodiment Construction

[0018] Embodiments of the present invention provide a leg assembly for a passenger seat that can provide improved flexibility that translates into better energy dissipation in its structural components.

[0019] figure 1 a) shows an embodiment of a leg assembly 100 incorporated into an embodiment of a seat frame 103 for a passenger seat, wherein each rear leg 101 is "divided" into two Sections: lower section 102 and upper section 104 . The bracket 106 is designed such that the lower portion 102 of the rear leg 101 is "combined" with the bracket 106 , ie is integral with the bracket 106 . The bracket 106 extends diagonally from the top of the front leg 108 down to the floor, ie to a rear mounting point 110 on the floor. The upper portion 104 of the rear leg 101 is off the floor and a joint 112 is formed between the upper portion 104 of the rear leg 101 and a bracket 106 which in turn connects directly to a rear mounting point 110 on the floor.

Abstract

A seat leg assembly for a passenger seat, a frame for a passenger seat, and a passenger seat. The seat leg assembly comprising a brace member configured to extend from a front end of a base frame of the passenger seat to a rear floor fitting; a front leg configured to extend from a front floor fitting to the brace member and connected to the brace member; a rear leg portion extending from a rear end of the base frame to the brace member; and a first joint structure connecting the rear leg portion to the brace member.

Description

technical field [0001] The present invention broadly relates to a leg assembly for a passenger seat, a seat frame for a passenger seat, and a passenger seat. More specifically, embodiments of the present invention relate to designing a chair leg assembly with improved load distribution and energy absorption capabilities. Background technique [0002] A standard economy class passenger seat for an aircraft includes a seat bottom, reclined seat back, and armrests, all supported by a structural frame mounted to laterally spaced leg assemblies. Among all the functions, the leg assembly plays two important roles in the structural composition of the passenger seat, which can be summarized as follows: [0003] 1. Keep the seat in place along the floor. [0004] 2. To absorb energy during the unlikely impact event to avoid collision. [0005] The survival rate of passengers during a plane crash depends on: the loads acting directly on the body, such as lumbar loads, the degree of...
