5、nger Seats in Transport Aircraft RATIONALE The use of oblique facing passenger seats has become prevalent for business and first class seating arrangements on many airlines. Industry standard test requirements and occupant injury criteria that suppliment the requirements of AS8049 are required for t

6、hese types of seats. This standard supersedes ARP6316. TABLE OF CONTENTS 1. SCOPE . 3 1.1 Purpose 3 1.2 Seat Types . 3 1.3 Units . 3 1.4 Use of Should and Shall . 3 2.

SCOPE 1.1 Purpose This SA

11、E Aerospace Standard (AS) documents a common understanding of terms, compliance issues, and occupant injury criteria to facilitate the design and certification of oblique facing passenger seat installations specific to Part 25 aircraft. The applicability of the criteria listed in this current releas

12、e is limited to seats with an occupant facing direction greater than 18 and no greater than 45 relative to the aircraft longitudinal axis. Seats installed at angles greater than 30 relative to the aircraft longitudinal axis must have an energy absorbing rest or shoulder harness and must satisfy the

13、criteria listed in Table 2. Later revisions are intended to provide criteria for other facing directions. Performance criteria for forward and aft facing seats are provided in AS8049 and for side facing seats in AS8049/1. This document contains the same content as superseded ARP6316 with additional

14、information included to align this Aerospace Standard with AS8049/1 regarding the use of the femur angular rotation sensor. Although the issues and criteria presented in this document are common with oblique facing seats installed in Part 23 aircraft and Parts 27 and 29 rotorcraft, these standards h

15、ave not been validated for these types of aircraft. 1.2 Seat Types This document presents standards for oblique facing passenger seats for use in aircraft type-certificated in the aircraft categories shown in Table 1.

31、m and provides descriptions of occupant forces and moments. These definitions are reproduced here for convenience together with additional definitions. Abdominal - Of or pertaining to the region of the body that contains the internal organs (excluding the respiratory and cardiac organs). It is bound

32、ed by the diaphragm and the pelvis. Cervical - Of or pertaining to the vertebrae in the neck that support the head and link the head to the spine. Neck Fz Force acting to move the head up or down. Positive in the up direction. Neck Mx Moment acting to move the head sideward. Positive in the directio

33、n of moving the left ear toward the left shoulder. Neck My Moment acting to move the head forwards or backwards. Positive in the direction of moving the head such that the chin approaches the sternum. Neck Mz - Moment acting to rotate the head. Positive in the direction of moving the chin towards th

34、e left shoulder. Nij A measure of neck injury calculated in accordance with 49 CFR 571.208 S6.6 (a). Occipital Condyle - The points where the skull attaches to the first cervical (neck) vertebra. Pelvic - Of or pertaining to the pelvis, which is commonly called the hip bone. Sternum - The Sternum is

35、 the long flat bone in the upper middle of the front of the chest linking the ribs and the collar bone. It is also called the breastbone. Thoracic - Of or pertaining to the thorax, which is the region of the body that includes the ribs and the sternum between the neck and abdomen. The thorax contain

36、s the respiratory and cardiac organs. SAE INTERNATIONAL AS6316 Page 6 of 14 2.3 General Definitions AIRBAG - An automatically inflated bag that deploys rapidly in the event of an accident and is positioned to protect the occupant from contact with the interior, or to alter the occupants head traject

37、ory. ATD - FAA HYBRID III - Adult male frontal crash tests device described in 49 CFR Part 572, Subpart E modified per SAE 1999-01-1609. (Reference FAA Policy Statement AIR-100-3-3-2000) ATD - HYBRID II - Adult male frontal crash test device which is described in 49 CFR Part 572, Subpart B. BARRIER

38、- A seat system feature or item of seat furniture that may form part of the occupant restraint system. The barrier may consist of a structural wall or an airbag (including structure mounted airbag (SMA) to limit occupant motion. CANT ANGLE - The seat track angle relative to the aircraft longitudinal

39、 axis. CONSERVATIVE - As used in this document, “conservative” means that the test article or test setup is more critical than the production part or installation. When determining what is conservative for occupant injury, select an article or setup based on properties that would make occupant injur

40、y more critical. HIC - HEAD INJURY CRITERION. Where head contact with seats, or other structure can occur, protection must be provided so that the head impact does not exceed a specified value of the Head Injury Criterion (HIC). HIC, as specified in AS8049C Section 5.3.9.4, considers the head cg res

41、ultant acceleration only after initial head contact with seats, or other structure occurs. In the calculation t1 and t2 are the points in time for which HIC is at a maximum. HIC 15 - As applied in Federal Motor Vehicle Safety Standards 49 CFR 571.208 S6.2(b)(1), considers the entire time history. In

42、 the calculations, t1 and t2 are any two points in time during the event, which are separated by not more than a 15 ms time interval, for which HIC is at a maximum. IMPACT - Impact is defined as the initial contact of the ATD with an object or surface. See also “Rebound”. Contact that does not resul

43、t in reversal of the direction of movement remains “impact” until such reversal occurs. NOMINAL SEATED POSITION(S) - The position(s) of the occupant when seated for taxi, takeoff and landing (TTL). OCCUPANT ANGLE - The angle of the occupant x-axis when in the nominal seated position relative to the

44、aircraft longitudinal axis. RATIONAL ANALYSIS - An analysis based on logic reason and basic engineering principles rather than actual data of the specific topic or item being examined. Data may be used to support a rational analysis. REBOUND - Rebound is ATD movement in approximately the opposite di

45、rection to the inertial direction irrespective of whether the ATD makes contact with anything. Contact that does not result in reversal of the direction of movement remains “impact” until such reversal occurs. SEAT SYSTEM - The seat, restraint system, cushions and barriers, and any furniture associa

46、ted with the seat installation, e.g., back shell, side console. SUBMARINING - Submarining occurs when an occupants movement allows the lap belt to slide over the pelvic bones into the soft abdominal tissue. TEST ANGLE - the angle of the occupant x-axis relative to the inertial load direction. SAE IN
