FIELD: transport, security systems. ^ SUBSTANCE: proposed device is placed on aircraft cabin passenger seats, connected to control unit arranged in cockpit. Note that the passenger cabin has cabin spin-scan video camera. Each passenger seat comprises seat-cushion, seat back and side members with armrests integrated into module allowing changing the seat geometrical structure in response to signal from the control unit. With rectangular frame in initial position, the upper and lower plates are arranged horizontally, feature invariable shape and are electrically insulated from the seat, and frame mounting place, respectively. The side vertical plates are made from alloy with mechanical shape memory effect and furnished with crosswise goffering and terminals arranged along the edges and connected to the control unit contacts corresponding to the seat number and to the electrical signal source. The frame side plate shape and sizes and, accordingly, the frame quadrangular configuration, given the control signal fed, allow inclining and moving the seat module with the passenger forward till rigid contact with the seat mounted ahead to lock the passenger. ^ EFFECT: higher safety. ^ 2 dwg |
