Description

Technical Field

[0001] This utility model belongs to the field of seat belt technology, specifically relating to a five-point seat belt. Background Technology

[0002] The five-point harness, as a core piece of personal protective equipment, has gradually developed into a mandatory safety standard in high-risk work fields since its invention in the mid-20th century. Its design principle is based on the theory of "multi-point force distribution," using a five-point restraint system at the shoulders, waist, and legs to distribute sudden impact forces to the torso and lower limbs, significantly reducing the risk of internal organ damage or bone fractures caused by single-point force. This device is widely used in construction, fire rescue, power maintenance, rock climbing and exploration, motorsports, and aircraft maintenance.

[0003] However, in current five-point safety harnesses, the stress is concentrated on the waist and hip connection area when suspended in operation. Especially under dynamic lifting or load conditions, the groin and hips are severely constricted. Long-term operation may cause soft tissue damage, and the discomfort can significantly distract the operator and increase the risk of high-altitude operations. Utility Model Content

[0004] To address the aforementioned technical problems, this invention designs a new five-point safety belt to solve the problem of chafing and groin constriction that often occurs with existing five-point safety belts, thus ensuring the safety of workers.

[0005] This utility model discloses a five-point safety harness, including a chest strap with a chest buckle, a waist belt connected to the middle of the chest strap with a waist buckle, and a left and right leg strap connected to the lower end of the chest strap, each with a left and right leg buckle. A rigid plate is fixedly connected to each of the left and right leg straps, with a bracket at the top of the rigid plate. A damper is fixedly installed inside the bracket, and a buffer seat is fixedly connected to the top of the damper. A buffer rod is fixedly connected to the top of the buffer seat, and a pressure seat is fixedly connected to the other end of the buffer rod. A sponge pad, shaped like a curved blade, is fixedly installed on the upper surface of the pressure seat. A guide block is fixedly installed on the side wall of the buffer seat, with a guide rod penetrating through the inner side of the guide block, and a first spring sleeved on the outer side of one end of the guide rod.

[0006] The chest buckle is blue, the waist buckle is red, and the left and right leg buckles are green and yellow, respectively.

[0007] A connecting strap is also provided between the rigid plates corresponding to the left and right leg straps.

[0008] The chest strap is connected to a hook via a connecting rope.

[0009] The guide rod passes through the inside of the guide block and is vertically connected to the inside of the bracket, and the outer diameter of the guide rod is adapted to the size of the hole opened on the inside of the guide block.

[0010] The beneficial effects of this utility model are:

[0011] Compared with existing technologies, this utility model's five-point safety belt integrates a multi-level cushioning system by setting rigid plates in the left and right leg straps, employing a damper and buffer rod linkage guiding mechanism, and combining a curved ergonomic foam pad to achieve gradient decomposition and pressure dispersion of impact force, effectively eliminating the hidden dangers of traditional safety belts chafing the groin and hips. The synergistic action of the guide block and spring allows the cushioning structure to adaptively adjust to the body's posture, ensuring uniform force distribution. Simultaneously, a visual guidance mechanism is constructed through a differentiated color-coded buckle system, significantly reducing the error rate of wearing the belt. This system achieves a systematic upgrade in safety performance from multiple dimensions, including human adaptability, operational error prevention, and structural impact resistance, comprehensively ensuring the safety of workers at heights.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] To address the issue of groin and hip chafing issues with existing five-point harnesses and ensure worker safety, please refer to [reference needed]. Figures 1 to 4 As shown, in this embodiment, a five-point safety harness is provided, including a chest strap 1, a chest buckle 14, a waist belt 15 connected to the middle of the chest strap 1, a waist buckle 16 on the waist belt 15, a left leg strap 2 and a right leg strap 3 connected to the lower end of the chest strap 1, and left leg buckles 17 and right leg buckles 18 respectively on the left leg strap 2 and right leg strap 3; a rigid plate 4 is also fixedly connected to the left leg strap 2 and right leg strap 3 respectively, and the top of the rigid plate 4 is provided with a... A bracket 5 has a damper 6 fixedly installed in its inner cavity. A buffer seat 7 is fixedly connected to the top of the damper 6. A buffer rod 8 is fixedly connected to the top of the buffer seat 7. A lower pressure seat 9 is fixedly connected to the other end of the buffer rod 8. A sponge pad 10 is fixedly provided on the upper surface of the lower pressure seat 9. The sponge pad 10 is shaped like a scimitar. A guide block 11 is fixedly provided on the side wall of the buffer seat 7. A guide rod 12 passes through the inner side of the guide block 11. A first spring 13 is sleeved on the outer side of one end of the guide rod 12.

[0022] In this embodiment, the chest strap 1 is first worn on the wearer's body and secured by it. Then, the wearer's legs are secured by the left leg strap 2 and the right leg strap 3 respectively. The wearer's buttocks then come into contact with the sponge pad 10. At this time, the sponge pad 10 experiences a longitudinal force and moves longitudinally. This longitudinal movement of the sponge pad 10 pushes the pressure seat 9, causing it to move longitudinally. The pressure seat 9's longitudinal movement, in turn, causes the buffer rod 8, which is fixedly connected to its bottom, to move longitudinally as well. This movement of the buffer rod 8 pushes the buffer seat 7, causing it to longitudinally compress the damper 6, which is fixedly connected to its bottom, thereby achieving damping. The deformation of the damper 6, along with the longitudinal movement of the buffer seat 7, causes the guide block 11 to slide along the guide rod 12, thereby improving the stability of the buffer seat 7 during longitudinal movement. The longitudinal movement of the guide block 11 compresses the first spring 13, which facilitates the subsequent deformation of the first spring 13. At this time, the reverse force generated by the deformation of the first spring 13 and the damper 6 can achieve the purpose of buffering and protection. Since there will be overweight groin entrapment during the ascent of high-altitude operations, and the groin area will also be entrapped by the straps during long-term work, the sponge pad 10 can increase the contact area with the buttocks to avoid groin entrapment and other phenomena when wearing it.

[0023] Furthermore, since the sponge pad 10 is curved, the area near the crotch can increase the crotch space of the person, avoiding discomfort caused by crotch compression. In addition, the area near the buttocks of the sponge pad 10 is larger, which can support the buttocks of the person, increase the force-bearing area, and improve comfort.

[0024] Reference Figure 2 and Figure 4 The guide blocks 11 are symmetrically distributed along the vertical center line of the buffer seat 7, and the guide blocks 11 and the guide rod 12 are perpendicular to each other. When the pressure seat 9 is subjected to longitudinal pressure, it will drive the buffer rod 8 to longitudinally compress the buffer seat 7 fixedly connected to the bottom. At this time, the longitudinal movement of the buffer seat 7 will drive the guide blocks 11 to slide along the guide rod 12.

[0025] Reference Figure 2 and Figure 3 The guide rod 12 passes through the inner side of the guide block 11 and is vertically connected to the inner side of the bracket 5. The outer diameter of the guide rod 12 is matched with the size of the hole opened on the inner side of the guide block 11. When the buffer seat 7 moves longitudinally, it drives the guide block 11 to move longitudinally as well. The guide block 11 will slide along the guide rod 12, thereby improving the stability of the buffer seat 7 during longitudinal movement.

[0026] To facilitate buckle differentiation and prevent incorrect wearing, the chest buckle 14 is blue, representing stability and calmness, consistent with the chest's role as a primary support point for the seatbelt. The waist buckle 16 is red, representing alertness and strength, reminding the user that the waist is a crucial part of the seatbelt's fixation. The left leg buckle 17 and right leg buckle 18 are green and yellow, respectively. Green represents safety and stability, reflecting the left leg's role as one of the supporting legs, while yellow represents attention and warning, echoing the right leg's auxiliary support function. By visually recognizing the color codes of the buckles, users can quickly determine the position and correspondence of each buckle. The color coding design is eye-catching, easy to distinguish, and not easily confused, ensuring rapid fastening even in emergency situations.

[0027] Furthermore, a connecting strap 19 is provided between the rigid plates 4 corresponding to the left leg strap 2 and the right leg strap 3, so that the elastic connecting strap 19 can adapt to changes in leg position during the movement of the person's legs.

[0028] Meanwhile, in order to connect the safety belt when performing high-altitude operations, a hook 21 is connected to the chest belt 1 via a connecting rope 20. The hook 21 can be used to hook the corresponding position when performing high-altitude operations to ensure work safety.

These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
