PADDED INSTRUMENT PANEL AND VISORS FOR AUTOMOTIVE VEHICLES

S1. Purpose and scope. This standard establishes requirements and test procedures for automotive vehicle instrument panel and sun visors designed to afford a reasonable degree of head protection in the event of a collision for front seat passengers wearing type 1 seat belt assemblies.

S2. Application. This standard applies to sedans, carryalls, station wagons, and light trucks up to 10,000 pounds G.V.W. This standard does not apply to that portion of the instrument panel directly in front of the steering wheel or to vehicles without a front passenger seat.

S3. The instrument panel including the padding assembly shall not contain any sharp or protruding rigid edges in the head impact The head impact area shall be determined by the use of a SAE two dimensional 50th percentile male manikin in midseat position wearing a type 1 seat belt assembly.

area.

The panel below the windshield shall be covered, at least in the impact area determined by the manikin, with energy absorbing cushioning material to cushion and spread the impact of a passenger's head. The structure of the instrument panel with padding in the impact area shall be designed to reduce the likelihood of injury to the passenger's head upon impact. For sedans and station wagons and when using the SAE Recommended Practice for Instrument Panel Laboratory Impact Test Procedure, SAE J921, the deceleration of the head form upon impact at 22 feet per second shall not exceed an effective maximum value of 80 g.'s in 60 milliseconds which value shall exclude all portions of the deceleration time curve of less than 3 milliseconds duration.

S3.1 The sun visors shall be constructed of or be covered by energy absorbing cushioning material. The sun visor mountings shall be designed and located to provide a reasonable degree of head protection.

[Federal Standard No. 515/3] RECESSED INSTRUMENT PANEL INSTRUMENTS AND CONTROL DEVICES FOR AUTOMOTIVE VEHICLES

S1. Purpose and scope. This standard establishes the location and identification of automotive vehicle instruments and control devices to afford a reasonable degree of protection in the event of a collision for front seat occupants wearing type 1 seat belt assemblies with seat in middle position. Occupant protection shall be determined by using a SAE two dimensional 50th percentile male manikin.

S2. Application. This standard applies to sedans, carryalls, station wagons, and light trucks up to 10,000 pounds G.V.W. Excluded are stand-up walk-in package delivery vehicles with tilt type drivers' seats.
