The work must be done according to a plan approved by the Secretary (the senior government official responsible for aviation safety).\n\n**Why it matters:** This improves crash protection by preventing occupants from \"submarining\" (sliding under a lap belt) during impact and reduces the risk of head and upper body injuries."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-22-25-front-seat-restraint-installations-modification","history":"/api/acts/ad-pa-22-25-front-seat-restraint-installations-modification/history","analysis":"/api/acts/ad-pa-22-25-front-seat-restraint-installations-modification/analysis","conflicts":"/api/acts/ad-pa-22-25-front-seat-restraint-installations-modification/conflicts","importantCases":"/api/acts/ad-pa-22-25-front-seat-restraint-installations-modification/important-cases","documents":"/api/acts/ad-pa-22-25-front-seat-restraint-installations-modification/documents"}}
