Triple-protection safety seat with telescopic straps

Abstract

The invention relates to a triple-protection safety seat with telescopic straps and mainly aims to solve the problem that an existing safety seat does not have safety protection measures for pressure bar breakage or pressure bar shaft breakage. The triple-protection safety seat is characterized in that a swing arm (9) is hinged to the backrest of a seat framework (1), the two straps (11) winds around guide wheels (10) and are connected with the swing arm (9), a locking oil cylinder (12) is hinged to a support (19) at the rear of the backrest of the seat framework (1), the oil cylinder rod end of the locking oil cylinder (12) is hinged to the swing arm (9), the locking oil cylinder (12) is a sealed oil cylinder, and an electromagnetic valve (11) and an energy accumulator (14) are serially connected between the rodless cavity and the rod cavity of the oil cylinder. The triple-protection safety seat has the advantages that if the upper half of a pressure bar breaks or a pressure bar shaft breaks, the telescopic straps can still effectively constraint a passenger, passenger safety is guaranteed, and high safety and comfortableness are achieved; the straps can be unfastened and fastened along with the ascending and descending of the pressure bar, and operation simpleness and high automation level are achieved.

Description

technical field [0001] The invention relates to a passenger seat of a large amusement device, in particular to a triple protection safety seat with a retractable back strap.
