CRASH-RESISTANT HELICOPTER SEAT INTEGRATED WITH MULTIPLE PROTECTIONS

摘要

Disclosed is a crash-resistant helicopter seat integrated with multiple protections. The crash-resistant helicopter seat comprises a main framework (1), a weighing sensor (2), a magnetorheological damping system (3), an upper trunk forced tensioning and rapid releasing system (4), a seat bucket (5), a multifunctional vest (6) and a controller, wherein the seat bucket (5) is in sliding connection with the main framework (1) in a vertical direction, the magnetorheological damping system (3) is fixedly arranged on the seat bucket (5), the magnetorheological damping system (3) is connected to the main framework (1) by means of the weighing sensor (2), the upper trunk forced tensioning and rapid releasing system (4) is arranged on the seat bucket (5), the multifunctional vest (6) is connected to the seat bucket (5) by means of the upper trunk forced tensioning and rapid releasing system (4), and the controller is separately connected to the weighing sensor (2) and the magnetorheological damping system (3). The technical solution has an excellent crash resistance and protection performance, can provide the optimal protection for all percentile passengers, enables a pilot to maintain an optimal attitude, prevents secondary collision, has a rapid release function, can realize one-key unlocking, and can meet life saving requirements of a pilot in various complex environments after a crash.
