Description

Technical Field

[0001] The invention relates to a safety belt buckle and belongs to the technical field of vehicle safety belts. Background Art

[0002] When a pregnant woman uses a three-point safety belt, the belt is placed horizontally across the abdomen. After a collision, the belt will compress the abdomen of the pregnant woman, posing a safety hazard.

[0003] In view of the above problems, the prior art has made corresponding improvements. One improvement is to add a net bag device to the triangular area formed by the safety belt, and to connect the lower safety belt (the safety belt placed horizontally at the abdomen) with a fixing belt to the seat cushion, so that the lower safety belt moves down to avoid the abdomen. This safety belt structure is relatively complex, and the position of the net bag device on the safety belt is difficult to adjust. Therefore, it is not adaptable to passengers of different body shapes, and the operation is relatively cumbersome. Another improvement is to add a safety pad. A card slot is provided on the front side of the safety pad. When in use, the installation pad is sat under the buttocks, and the safety belt originally placed horizontally at the abdomen passes through the card slot to avoid the abdomen. When in use, since the pad is sat under the buttocks, the insertion operation of the safety belt is relatively difficult. In addition, in the event of a collision, the pad is also easy to fall out and it is difficult to play its due role. Summary of the invention

[0022] The present invention will be further described below in conjunction with the embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading this description, various equivalent modifications of this description by those skilled in the art all fall within the scope defined by the appended claims of this application.

[0023] Please refer to Figures 1 to 5 As shown, the seat belt buckle for pregnant women in this embodiment includes a buckle bottom shell 1, a pressing cover 2 and a switch. The buckle bottom shell 1 is connected to the middle part of the front side of the seat cushion of the vehicle seat 10, that is, in front of the crotch of the occupant. The seat belt 9 that is horizontally arranged at the abdominal position of the original three-point seat belt 9 forms a V shape after passing through this seat belt buckle for pregnant women to fix the root of the thighs of the occupant. In this embodiment, two connecting shafts 101 are provided on the bottom side of the buckle bottom shell 1, and a connecting belt 3 is fixed at the middle part of the front side of the seat cushion of the vehicle seat 10. The connecting shafts 101 are inserted into the connecting belt 3, thereby completing the connection between the buckle bottom shell 1 and the vehicle seat 10. By using the connecting belt 3 for connection, when this seat belt buckle for pregnant women is not needed, it can be turned down under the vehicle seat 10, which is flexible and convenient. If the connecting belt 3 is provided with an adjustable length, it can be more convenient to adjust the position of the seat belt buckle for pregnant women according to needs.

[0024] On the upper edge of the first side of the buckle bottom shell 1, there are two base rotating shaft seats 102 for installing a rotating shaft to form a hinge joint with the pressure cover 2, so as to form an openable and closable structure between the pressure cover 2 and the second side of the buckle bottom shell 1. The first side and the second side of the buckle bottom shell 1 are opposite sides. A transverse through groove 103 is provided on the buckle bottom shell 1, and the top of the through groove 103 is open. The through groove 103 enables the seat belt 9 to freely move through in its stretching direction (transverse). When the pressure cover 2 is closed on the buckle bottom shell 1, the pressure cover 2 seals the top of the through groove 103 to form a passage for the seat belt 9 to pass through transversely. When the pressure cover 2 is opened, the top of the through groove 103 is open, and the seat belt 9 can be taken out from the through groove 103. In order to improve the convenience of operating (opening and closing the pressure cover 2) after the seat belt 9 is set in the pregnant woman seat belt buckle, the first side of the buckle bottom shell 1 is defined as the side of the buckle bottom shell 1 close to the backrest of the seat 10, that is to say, the opening and closing side of the pressure cover 2 faces the front of the seat 10, so that there is enough space for operation.

[0025] It should be noted that the through groove 103 on the buckle bottom shell 1 is not necessarily recessed in the buckle bottom shell 1. As shown in this embodiment, a switch guiding shaft seat 104 is provided on the upper edge of the second side of the buckle bottom shell 1, and the switch guiding shaft seat 104 protrudes from the buckle bottom shell 1. When the pressure cover 2 is closed, it is closed on the top of the switch guiding shaft seat 104. Therefore, the through groove 103 as described above is formed between the base rotating shaft seat 102 and the switch guiding shaft seat 104 on the buckle bottom shell 1.

[0026] The opening and closing of the pressure cover 2 on the buckle bottom shell 1 is controlled by a switch. The switch includes a switch body 4. The buckle bottom shell 1 is provided with a sliding groove 105, and the switch body 4 is arranged in the sliding groove 105 and slidably connected with the buckle bottom shell 1. A transverse guiding shaft 5 is provided on the switch guiding shaft seat 104 of the buckle bottom shell 1, and the switch body 4 is sleeved on the guiding shaft 5 and guided by the guiding shaft 5. A return spring 6 is sleeved on the guiding shaft 5 between the switch body 4 and the switch guiding shaft seat 104. In addition, the switch body 4 is provided with an operating part 401 protruding from one end of the buckle bottom shell 1. When the operating part 401 is pressed, the switch body 4 moves transversely along the guiding shaft 5 in the sliding groove 105. When the switch body 4 is not operated, the switch body 4 is located at the first position in the sliding groove 105. When the switch body 4 is in this position, the pressure cover 2 can be kept closed. When the operating part 401 is pressed (pushed), the switch body 4 moves transversely, compressing the return spring 6. The switch body 4 is located at the second position in the sliding groove 105. When the switch body 4 is in this position, the pressure cover 2 can be opened, so as to take out the seat belt 9 from the buckle bottom shell 1. It is easy to understand that the return spring 6 makes the switch body 4 have a tendency to slide to the first position and stay. That is to say, when the switch body 4 is not operated, the switch body 4 is in the first position under the action of the return spring 6.

[0027] The fit between the gland 2 and the switch body 4 is in the form of a snap hook. The front side of the gland 2 (corresponding to the second side of the snap - bottom shell 1) is provided with a downward - turned hook body 201, and the switch body 4 is provided with a forward - protruding hook tongue 402. When the switch body 4 is in the first position, the hook tongue 402 cooperates with the hook body 201 to form a snap between the switch body 4 and the gland 2, so that the gland 2 cannot be opened. When the switch body 4 is in the second position, the hook tongue 402 and the hook body 201 are offset from each other, and the switch body 4 and the gland 2 are disengaged from the snap state.

[0028] In order to improve the stability when the gland 2 is closed and prevent the accidental opening of the gland 2, the pregnant - woman seat - belt buckle of this embodiment is also provided with a safety cover 7. Specifically, the safety cover 7 is hinged to the second side of the snap - bottom shell 1. The safety cover 7 is provided with a first part 701 and a second part 702, and the first part 701 and the second part 702 are combined to form an L - shaped structure. The two ends of the second side of the snap - bottom shell 1 are provided with safety - cover rotating shafts 8, and the second part 702 of the safety cover 7 is hinged to the snap - bottom shell 1 through the safety - cover rotating shafts 8.

[0029] The rotation of the safety cover 7 makes it have a first state and a second state. When the safety cover 7 is in the first state, the first part 701 of the safety cover 7 is located on the opening - and - closing path of the gland 2 to prevent the gland 2 from being opened, that is, the first part 701 of the safety cover 7 is located above the gland 2. When the safety cover 7 is in the second state (the safety cover 7 rotates forward), the first part 701 of the safety cover 7 deviates from the opening - and - closing path of the gland 2. In this state, the gland 2 can be opened. In order to enable the safety cover 7 to stably stay in the first state, a first protrusion 202 is provided on the side of the gland 2 facing away from the snap - bottom shell 1 (the upper side of the gland 2), and a second protrusion 703 is provided on the first part 701 of the safety cover 7. When the safety cover 7 is in the first state, the safety cover 7 covers the second side of the snap - bottom shell 1 and the opening - and - closing side of the gland 2, redundantly reinforcing the gland 2, and the first protrusion 202 is located on the back side of the second protrusion 703 to block the change of the safety cover 7 to the second state.

[0030] When the buckle device of the present invention is used, first rotate the safety cover 7 to the second state, then push the switch to move to the second position, overcoming the elastic force of the return spring 6. After the switch moves to the second position, the switch body 4 and the gland 2 are disengaged from the snap state, and the gland 2 is opened. Press the seat - belt 9 flatly into the through - slot 103 of the buckle base, then cover the gland 2, release the switch, and under the action of the return spring 6, the switch returns to the first position to snap - lock the gland 2 with the gland 2, and then rotate the safety cover 7 to the first state to complete the connection of the buckle.
