[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Example 1, such as Figure 1 As shown, a flight safety harness device includes a retractor 1 connected to a shoulder strap 2, the shoulder strap 2 being arranged in a herringbone shape, a waist belt 3 connected to the bottom two sides of the shoulder strap 2, a buckle component 4 installed between the two waist belts 3, a waist belt adjuster 5 installed in the middle of the waist belt 3, and a fixing piece component 6 installed on the outer side of the waist belt 3.
[0022] In this embodiment, when the aircraft encounters an emergency, such as rapid acceleration, deceleration, turbulence, or airflow impact, the retractor 1 will immediately lock the shoulder strap 2, preventing the shoulder strap 2 from being pulled out further, thus firmly securing the passenger to the seat and preventing injury to the passenger due to inertia, greatly improving safety and comfort during flight.
[0023] The seat belt adjuster 5 and retractor 1 can adjust the length and tightness of the seat belt according to the user's body size and clothing to ensure that the seat belt provides a reliable fixation effect without making the user feel overly restricted, thereby improving comfort.
[0024] This seatbelt securely fastens the user to the seat via a retractor 1 (shared by both shoulder straps) and two fixing components 6 (two at the hips). This method effectively restricts the user's body movement in all directions, whether forward, backward, left, right, or upward. When the aircraft accelerates, decelerates, turns, bumps, or encounters airflow, it prevents the user from slipping off the seat or colliding with surrounding objects. Furthermore, in the event of an emergency, such as sudden braking (which may occur during aircraft landing) or a collision, this seatbelt can evenly distribute the impact force on the body to the shoulder straps 2 and lap belts 3, providing particularly effective protection for the upper body.
[0025] Example 2, as Figure 1 As shown, this embodiment adds the following structure to the embodiment 1: an inertial sensor is installed inside the retractor 1.
[0026] In this embodiment, by setting the inertial sensor, when the flying body encounters an emergency situation, such as sudden acceleration, deceleration, jolt or encounters airflow impact, the inertial sensor in the retractor 1 can quickly detect abnormal acceleration change, and once the acceleration reaches the set threshold, the shoulder belt 2 will be immediately locked, so that the shoulder belt 2 cannot continue to be pulled out, and the passenger is firmly fixed on the seat, improving the safety of use.
[0027] As shown in Embodiment 3, Figure 2 The retractor 1 includes a frame 7, a mandrel 8 movably mounted in the frame 7, the shoulder belt 2 arranged on the mandrel 8, a coil spring component 9 mounted on one side of the frame 7, the coil spring component 9 connected to one side of the mandrel 8, a pawl 10 mounted on the other side of the mandrel 8, a ratchet component 11 connected to the pawl 10, an inertia block 12 connected to the ratchet component 11, a spring 13 mounted on one side of the inertia block 12, a mechanical cover 14 connected to the other side of the spring 13, and the mechanical cover 14 mounted on the other side of the frame 7.
[0028] In this embodiment, when the shoulder belt 2 is quickly pulled, the inertia block 12 moves relative to the ratchet component 11, and the inertia overcomes the resistance of the spring 13 to trigger the ratchet component 11 to lock the internal gear of the mechanical cover 14, thereby driving the pawl 10 to eccentrically move and lock with the gear of the frame 7, stopping the movement of the mandrel 8 and blocking the shoulder belt 2, thereby preventing the shoulder belt 2 from being continuously pulled out, so that the shoulder belt 2 is in a locked state, protecting the occupant, and the retractor 1 can recover the shoulder belt 2 through the coil spring component 9 to maintain a proper length for use.
[0029] As shown in Embodiment 4, Figure 1 The shoulder belt 2 and the waist belt 3 are fixedly connected by fixed sewing.
[0030] In this embodiment, during production, the shoulder belt 2 and the waist belt 3 are fixedly connected by fixed sewing, which is more convenient to process and stable in connection.
[0031] As shown in Embodiment 5, Figure 3 The waist belt 3 includes a first waist belt 15 and a second waist belt 16, the lock component 4 is mounted between the two first waist belts 15, the shoulder belt 2 is fixedly sewn on the first waist belt 15, the waist belt adjuster 5 is mounted between the first waist belt 15 and the second waist belt 16, and the fixed sheet component 6 is mounted on the second waist belt 16.
[0032] In the embodiment, the distance between the first waist belt 15 and the second waist belt 16 can be adjusted by the waist belt adjuster 5 when in use, the two first waist belts 15 can be connected by the buckle part 4, and the safety belt can be unfastened by the buckle part 4 in a short time, so as to quickly leave the seat and escape in an emergency.
[0033] The above embodiment only illustrates the principle and effect of the utility model, and is not used to limit the utility model. Any person skilled in the art can modify or change the above embodiment without departing from the spirit and category of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
