Seat and protection device of seat

Abstract

The invention relates to a seat and a protection device. The protection device comprises a left pressing plate, a left rotating shaft, a left ratchet wheel, a left pawl, a left unlocking device, a right pressing plate, a right rotating shaft, a right ratchet wheel, a right pawl and a right unlocking device; the left pressing plate is fixed to the left rotating shaft, the left ratchet wheel is arranged at one end of the left rotating shaft, and the left unlocking device is fixedly connected with the left pawl and controls the left pawl to move to lock or unlock the left ratchet wheel; the rightpressing plate is fixed to the right rotating shaft, the right ratchet wheel is arranged at one end of the right rotating shaft, the right unlocking device is fixedly connected to the right pawl andcontrols the right pawl to move to lock or unlock the right ratchet wheel, a one-way bearing is arranged between the left rotating shaft and the left ratchet wheel, and a one-way bearing is arranged between the right rotating shaft and the right ratchet wheel. After the left pressing plate and the right pressing plate are combined, a heart-shaped space is formed, the space conforms to the shape ofthe abdomen of a human body, the waist holding type protection effect is achieved, the safety is high, the degree of freedom of the upper part of the body and the legs of a passenger is high, ridingis more comfortable, and the device is specially suitable for row seat application.

Description

technical field [0001] The invention relates to the technical field of amusement equipment, in particular to a protective device for a seat and a seat using the protective device. Background technique [0002] Amusement equipment generally has a certain degree of danger, so it is necessary to install a protective device on the seat. During the amusement process, the protective device can limit the passengers on the seat to avoid the accidental danger caused by the passenger leaving the seat without authorization. The existing There are mainly shoulder pressure bars, front abdominal pressure bars and waist pressure bars in the technology. The shoulder pressure bars hold the upper body of passengers, which is characterized by safety and reliability. The disadvantage is that the structure is too large, which restricts passengers too much and lacks comfort; the front pressure bar The abdominal bar is a T-shaped bar installed in front of the seat. The cross bar of the T-shaped ba...

[0002] Amusement equipment generally has a certain degree of danger, so it is necessary to install a protective device on the seat. During the amusement process, the protective device can limit the passengers on the seat to avoid the accidental danger caused by the passenger leaving the seat without authorization. The existing There are mainly shoulder pressure bars, front abdominal pressure bars and waist pressure bars in the technology. The shoulder pressure bars hold the upper body of passengers, which is characterized by safety and reliability. The disadvantage is that the structure is too large, which restricts passengers too much and lacks comfort; the front pressure bar The abdominal bar is a T-shaped bar installed in front of the seat. The cross bar of the T-shaped bar presses the passenger's abdomen, and the upper body of the passenger is relatively free. The disadvantage is that there is a bar between the passenger's legs, which hinders the movement of the legs; the ring waist press The bar uses a semi-arc-shaped pressure bar to hoop the passenger's abdomen. The feature is that the passenger's upper body and legs have a large degree of freedom and high comfort. The disadvantage is that the semi-arc-shaped pressure bar takes up more space when it is opened, and the seat is not open enough. , passengers are restricted in getting in and out of the seats, so the longitudinal spacing of the seats can only be increased, there is room for improvement
