This lock out mechanism must have various lock out sots to accommodate 5th percentile female (109.8lb ) to 95th percentile male occupants as defined in ASTM F1166-07. The weight of the 95th percentile male occupant is 267 lb (121.2 kg). 3.3.16. 3.4. Suspension detail requirements. 3.4.1. Seat suspension is required to be optimized for the LCAC operational environment. LCAC operational testing determined that suspension range shall be between 5 and 6 inches. The maximum allowable suspension travel is limited due to the operator controls interface and overhead clearance restrictions. 3.4.2. Suspension systems with a ratio of 1:1 between vertical seat travel suspension systems are technically acceptable. The ratio is calculated by dividing the vertical seat travel by the suspension stroke. 3.4.3. . Suspension/shock modules between all seat types must be interchangeable to allow casualty suspensions seats to be replaced during deployment. 3.4.4. Seat suspension is required to operate without the use of electrical power. 3.4.5. The seat suspension must be adjustable per the occupant weight. The seat must have a gauge or measuring device to measure suspension setting for occupant weight. The suspension system will utilize an air spring/damper. 3.4.6. Seats shall be capable of mitigating dynamic exposure to levels below acceptable limits as specified in ISO Standards 2631 Part 1 (1997) & Part 5 (2001) (see attachment) and as specified in sections 14.4.5 of ASTM F1166-07. For an exposure duration of 4 hours in the LCAC operational environment, the weighted acceleration (aw) is required to be 1.35 m/s2 or below in the frequency range of 0.5 to 80 Hz and should strive to be 0.55 m/s2 or below as an objective. The offeror should provide simulation results that show the lowest achievable weighted acceleration value for this operational environment. LCAC acceleration data is provided. Equations to calculate the weighted acceleration are given in ISO Standard 2631 Part 1. 3.4.7. The suspension shall move the seat backrest and seat pan together in order to prevent operator discomfort. Seats will also provide lock out feature in-case of suspension/adjustability failure. 3.4.8. The suspension travel will prevent the seat from hitting the suspension stops during an acceleration event 10 times the acceleration of gravity at sea level when the seat occupant is the 95th percentile male. 3.5. Detail requirements for Craftmaster style seats. 3.5.1. Seating shall be provided in the Command Module as follows: Command Module: Craftmaster Seat (1) Command Deck Engineer Seat (1) Command Deck Navigator Seat (1) Command Deck Wave Commander Seat (1) Command Deck 3.5.2.

Craftmaster style crew seats shall be interchangeable. 3.5.4. Adjustment. 3.5.4.1. Seats shall be compatible with seat tracks per NAVSEA drawing 662-5749737E. Seats shall be mounted on sliding tracks to permit fore and aft movement of at least 12 inches adjustment in increments of 1 inch. The seat tracks for each seat are located 13 inches apart measured from the track centerline. The seat track geometry and existing adjustment holes may be utilized. Note that parts may be mounted to the existing seat tracks to provide adjustability; however, additional parts may not be higher than the existing seat track which is 0.5" above the deck Additional parts may not require any modification to the craft or tracks for integration. Offeror will not use existing sliding mechanism from existing LCAC seats (where the seat physically attaches to the track). 3.5.4.2. Vertical adjustment shall be no less than 4.5 inches in increments no greater than 1/2 inches. 3.5.5. Dimension tolerance. 3.5.5.1. Seat cushion shall be 19.5 inches in order to fit in the LCAC. Given that many commercial seats will not meet this dimension, allowance is given for the seat to be modified from the original commercial design to meet this tolerance. 3.5.5.2. The vertical distance between the top of the seat tracks and the seat reference point (SRP) as defined in MIL-STD-1472G (see attachment) shall be no greater than 11.00 inches. This distance shall be measured with the seat adjusted in the lowest vertical position with the suspension at full extension.
