The window breaker 1 includes a window breaker body 101 and a cover body 102. A window breaking assembly 103 and a safety belt cutting assembly 104 are respectively provided at both ends of the window breaker body 101. The two covers 102 respectively cover the window breaking assembly 103 and the safety belt cutting assembly 104.

[0034] In this embodiment, the restraint belt 2 is an elastic belt that passes around the two ends of the window breaker 1 in a direction perpendicular to the extension direction of the safety belt 3, and surrounds the window breaker 1 and the safety belt 3 to form a surrounding constraint, thereby binding and securing the window breaker 1 to the safety belt 3. In this embodiment, the restraint belt 2 is a single long belt structure, the main body section of which is attached to the front of the window breaker 1. The two ends of the restraint belt 2 pass around the cover 102 at both ends of the window breaker 1 and are connected to the connecting plate 4 on the back side of the safety belt 3 (see Figure 3 ). The connection between the restraint belt 2 and the connecting plate 4 can be achieved by: hooks 8 are respectively provided at both ends of the connecting plate 4, and hanging holes 201 are provided at the two free ends of the restraint belt 2 and are hooked on the hooks 8. Furthermore, in order to facilitate the grasping of the end of the restraint belt 2, a finger grasping portion 202 is provided at one end of the restraint belt 2, and anti-slip stripes can be provided on the finger grasping portion 202. It should be noted that the above-mentioned connection method is only an exemplary description, and the protection scope of this patent is not limited to this specific implementation structure. Any connection scheme that forms an unlockable fit with the connecting plate 4 through any end of the restraint belt 2 should be deemed to fall within the protection scope of this patent. The unlockable fit includes but is not limited to hook connection, snap connection, plug-in fit or other mechanical connection methods that can achieve quick assembly and disassembly. As long as the connection structure can meet the technical requirements of reliable connection between the restraint belt 2 and the connecting plate 4 under normal use, and can be easily unlocked and separated when needed, it belongs to the technical solution covered by the claims of this patent.

[0035] See also Figure 2 、 Figure 4 In this embodiment, in order to prevent the window breaker 1 from sliding on the safety belt 3 and to provide stability of the connection, anti-slip particles 5 are provided on the contact surface between the window breaker 1 and the safety belt 3 and on the contact surface between the connecting plate 4 and the safety belt 3.

[0036] In order to constrain the movement path of the restraining belt 2 and prevent it from sliding on the window breaker 1, restraining mechanisms for guiding and constraining the movement path of the restraining belt 2 are provided at both ends of the window breaker 1 and on the surface where the window breaker 1 contacts the restraining belt 2.

[0037] To solve the problem of parts being lost after disassembly, in this embodiment, an anti-separation mechanism 7 is provided between the window breaker 1 and the restraining belt 2. The anti-separation mechanism 7 restricts the middle section of the restraining belt 2 to the window breaker 1, so that the restraining belt 2 remains connected to the window breaker 1 after the surrounding restraint is released. Figure 1 、 Figure 2 In this embodiment, the anti-separation mechanism 7 employs a through-type limiting mechanism, comprising a limiting groove 701 formed on the surface of the window breaker 1 and a connecting member 702 extending across the limiting groove 701. The middle section of the restraining strap 2 is accommodated within the limiting groove 701 and is prevented from being released by the connecting member 702. The connecting member 702 is a ribbed plate with both ends fixed to the sidewalls of the limiting groove 701. During use, one end of the restraining strap 2 is passed under the connecting member 702. Alternatively, the connecting member 702 can be two ribbed plates, one connected to each side of the limiting groove 701 and with a gap between them, allowing the restraining strap 2 to be inserted laterally through the gap and into the bottom of the connecting member 702.

[0038] See also Figure 4 In order to prevent the lateral displacement of the safety belt 3, a limiting strip 9 is provided on the side of the cover 102 at both ends of the window breaker 1 close to the safety belt 3, which is consistent with the extension direction of the safety belt 3. The spacing between the two limiting strips 9 is adapted to the width of the safety belt 3, and the safety belt 3 is located between the two limiting strips 9 to form a lateral positioning.

[0039] Example 2

[0040] See also Figure 5 、 Figure 6 The difference between this embodiment and embodiment 1 is that the middle main section of the restraint belt 2 is abutted against the back of the safety belt 3. The two ends of the restraint belt 2 pass around the cover bodies 102 at both ends of the window breaker 1 and are connected to the hooks 8 provided on the front of the window breaker 1.

[0041] Example 3

[0042] See also Figure 7 This embodiment differs from Example 1 in that the restraining mechanism for guiding and restricting the movement of the restraining band 2 is a flange 602 located on either side of the restraining band 2 and protruding from the window breaker body 101 and cover 102. The anti-separation mechanism is a limiting boss 703 protruding from the window breaker 1. A socket hole 704 is provided in the middle section of the restraining band 2. The limiting boss 703 passes through the socket hole 704 and has an enlarged head at its top with a radial dimension larger than the diameter of the socket hole 704.
