Description

Technical Field

[0001] This invention relates to a vehicle seat belt connection device, and more specifically, to a vehicle seat belt connection device that enables quick and easy installation of seat belts in a vehicle. Background Technology

[0002] Car seats are typically equipped with seat belts to protect passengers from impacts in an accident.

[0003] Traditional three-point seat belts include: a retractor installed at the bottom of the vehicle's B-pillar, a shoulder anchor installed at the top of the vehicle's B-pillar, a lower anchor anchored on the side of the vehicle body facing the B-pillar, a webbing extending from the retractor and anchored to the lower anchor via the shoulder anchor, a tab on the webbing, and a buckle anchored on the other side of the seat and engaging with the tab.

[0004] When these traditional vehicle seat belts need to be installed on or removed from a vehicle for maintenance, a pneumatic tool must be inserted between the seat and the B-pillar to connect or disconnect the tab to or from the lower anchor. However, the problem is that the webbing cannot be installed and removed quickly because the space between the seat and the B-pillar is very narrow.

[0005] Technical issues

[0006] The present invention aims to solve the above-mentioned problems and its purpose is to provide a vehicle seat belt connection device that can quickly and easily remove the webbing from the lower anchor. Summary of the Invention

[0007] To achieve the above objectives, the vehicle seat belt connection device according to the present invention includes: a first tongue plate disposed at the end of the webbing; a fixing bracket fixed to the first tongue plate; a lower anchor having a second tongue plate, the second tongue plate being assembled to the fixing bracket and fixed to the vehicle body under the seat; and a locking element installed inside the fixing bracket for locking or unlocking the second tongue plate inserted into the fixing bracket.

[0008] Furthermore, the fixing bracket may include a front bracket and a rear bracket, which combine to form an opening into which the top of the second tongue plate is inserted. In this case, the locking element may be mounted on the fixing bracket to lock the second tongue plate inserted into the opening of the fixing bracket when moving forward, and to release the locking state of the second tongue plate when moving backward and downward.

[0009] Furthermore, the locking element may include: a lifting block installed inside the fixed bracket and located above the locking button; a first elastic member that provides a downward force to the lifting block to press the locking button downward; and a second elastic member installed on the rear bracket to press the unlocked locking button forward.

[0010] On the other hand, the locking element may include a support mounted on the rear bracket, the support being used to restrict the rearward movement of the locking button so that the locking button moving forward will not be unlocked by being forced to move backward.

[0011] In this configuration, the lifting block may include: a main body located inside the fixed bracket and pressing down on the front end of the locking button; and a left wing and a right wing protruding from both sides of the main body and pressed upward by a second tongue plate inserted into the fixed bracket.

[0012] Furthermore, a receiving groove can be formed on the lower surface of the body of the lifting block. In this case, a blocking block can be formed on top of the locking button. When the locking button is forced to move backward, the blocking block disengages from the receiving groove and interferes with the rear of the body of the lifting block, thereby restricting the forward movement of the locking button.

[0013] Furthermore, the second elastic member can be a spring sheet that undergoes elastic deformation when pressed against a locking button that moves backward due to an external force.

[0014] Furthermore, a vertical opening slot can be formed at the top of the second tongue plate, into which the body of the lifting block and the front end of the locking button are vertically inserted. In this case, a horizontal slot can be formed at the bottom of the vertical opening slot, into which the rear end of the forward-moving locking button is inserted.

[0015] Furthermore, the rear end of the locking button may be configured to extend at an inclined angle on both sides along the horizontal groove to facilitate entry into the horizontal groove.

[0016] Beneficial effects of the invention

[0017] The vehicle seat belt connecting device of the present invention, with the above structure, allows for easy connection of the webbing to the lower anchor by simply inserting the fixing bracket fixed to the end of the webbing into the lower anchor; and allows for easy separation of the webbing from the lower anchor by simply pressing the locking button backward; at the same time, since the webbing will not separate from the lower anchor unless the locking button is pressed, it also has the effect of ensuring stability.

Conversely, when an element such as a layer, film, region, or substrate is referred to as being “below” another element, it may be directly below the other element, or there may be intermediate elements present.

[0062] Furthermore, as used in this article, ordinal numbers such as “first” and “second” can be used to describe various components, but these components are not limited by these terms, which are only used to distinguish one component from another.

[0063] Hereinafter, in describing embodiments of the present invention in detail with reference to the accompanying drawings, the same reference numerals will be used for the same structures, and for clarity, the different parts will be described primarily.

[0064] like Figures 1 to 7 As shown, the vehicle seat belt connection device according to the present invention includes: a first tongue plate 100 disposed at the end of the webbing W; a fixing bracket 200 fixed to the first tongue plate 100; a lower anchor 300 having a second tongue plate 310, the second tongue plate 310 being assembled into the fixing bracket 200 and fixed to the vehicle body below one side of the seat (under the seat); and a locking element 400 installed inside the fixing bracket 200 for locking or unlocking the second tongue plate 310 assembled to the fixing bracket 200.

[0065] The fixed bracket 200 may include a front bracket 210 and a rear bracket 220, which are combined at the bottom to form an opening into which the top of the second tongue plate 310 can be inserted.

[0066] In this case, a matching hook 211 and a matching groove 221 corresponding to the matching hook 211 can be formed on the front bracket 210 and the rear bracket 220, respectively.

[0067] The fixing bracket 200 is preferably configured to protect itself from external impacts and foreign objects by a separate cover 201.

[0068] The locking element 400 includes: a locking button 410; a lifting block 420 mounted inside the fixed bracket 200 and located above the locking button 410; a first elastic member 430 that provides a downward force to the lifting block 420 to press the locking button 410 downward; and a second elastic member 440 mounted on the rear bracket 220 to press the unlocked locking button 410 forward.

[0069] The locking button 410 is movably mounted inside the fixed bracket 200 to move up and down and back and forth, and locks the second tongue plate 310 inserted into the opening of the fixed bracket 200 when moving forward, and unlocks the second tongue plate 310 when moving backward and downward.

[0070] The locking button 410 is pushed upwards and abuts against the second tongue plate 310 in the insertion opening.

[0071] In this case, the front bracket 210 may have a first guide hole 212, into which the front end 411 of the locking button 410 may be inserted, so that the locking button 410 can move stably back and forth and up and down; the rear bracket 220 may have a second guide hole 222, into which the rear end 412 of the locking button 410 may be inserted.

[0072] On the other hand, a through groove 202 is formed on the cover 201, through which the front end 411 of the locking button can pass so that the operator can press the locking button 410, which will be described below.

[0073] In this configuration, the through-slot 202 is formed so that the interior is visible from the outside of the cover 201, allowing inspection of the operation of the locking button 410 and the lifting block 420. This is to facilitate visual confirmation of the locking and unlocking status, including situations where the lock is not properly engaged.

[0074] The lifting block 420 may include: a body 421 located inside the fixed bracket 200 and pressing down on the locking button 410; and a left wing and a right wing 422 protruding on both sides of the top of the body 421 and pressed up by the second tongue plate 310 assembled to the fixed bracket 200.

[0075] On the other hand, a forward protrusion 423 is formed on the main body 421 of the lifting block 420 to stabilize the lifting movement of the lifting block 420, and the front bracket 210 preferably has a third guide hole 213 formed vertically, into which the forward protrusion 423 of the lifting block 420 can be inserted. The third guide hole 213 is formed above the first guide hole 212.

[0076] The first elastic member 430 may be a compression helical spring, with its upper end fixed to the fixed bracket 200 and its lower end fixed to the upper end of the lifting block 420.

[0077] In this configuration, the top of the lifting block 420 may have an upper protrusion 425, on which the lower end of the first elastic member 430 may be fitted and fixed. Furthermore, the front bracket 210 and the rear bracket 220 may each have a fixed end 223, on which the upper end of the first elastic member 430 may be fixed.

[0078] The second elastic member 440 is installed at the rear of the rear bracket 220, facing the second guide hole 222, and is elastically deformed backward by being pressed by the rear end 412 of the locking button 410, which is forced to move backward by the operator's pressing action. At this time, the locking button 410 is in the unlocked state of the second tongue plate 310 and is continuously subjected to the forward moving force of the second elastic member 440.

[0079] On the other hand, a vertical opening groove 311 is formed on the top of the second tongue plate 310, into which the main body 421 of the lifting block 420 and the front end 411 of the locking button 410 can be vertically inserted.

[0080] Furthermore, a horizontal opening groove 312 is formed at the lower end of the vertical opening groove 311, into which the rear end 412 of the forward-moving locking button 410 can be inserted.

[0081] In this case, the rear end 412 of the locking button 410 is preferably formed to extend obliquely along both sides of the horizontal opening slot 312 so as to facilitate entry into the horizontal opening slot 312.

[0082] In one aspect, the second elastic member 440 may be a spring sheet, the upper end of which is fixed to the rear surface of the rear bracket 220.

[0083] In addition, a support member 450 can be installed on the rear bracket 220.

[0084] The support member 450 is a horizontal bar that spans the lower part of the second guide hole 222. It restricts the backward movement of the locking button 410, preventing the forward-moving locking button 410 from being forced backward and thus releasing the locked state. Therefore, the locked state can be stably maintained.

[0085] Although this embodiment shows the support 450 being secured by fitting both ends into matching hooks 211 formed on the front bracket 210 to prevent the paired front bracket 210 and rear bracket 220 from separating, it is not limited to this example and can also be configured to be directly secured to the rear of the rear bracket 220.

[0086] Preferably, a blocking block 413 is formed on the top of the locking button 410, and a receiving groove 424 for accommodating the blocking block 413 is formed on the lower side of the body 421 of the lifting block 420.

[0087] In this configuration, the blocking block 413 is housed in the receiving groove 424 in the locked state. Then, when the locking button 410 is forcibly moved backward to unlock, the movement of the locking button 410 is restricted by separating the locking button 410 from the receiving groove 424 and interfering with the rear surface of the body 421 of the lifting block 420. Therefore, the unlocked state can be stably maintained.

[0088] Using the vehicle seat belt connection device of the present invention configured as described above, the webbing W can be quickly and easily installed onto and removed from the lower anchor 300 fixed to the vehicle body below one side of the seat.

[0089] like Figure 5As shown in A and 6A, when the operator wants to connect the webbing W to the lower anchor 300, the cover 201 is used to move the fixing bracket 200 downwards, and the upper part of the lower anchor 300 is inserted into the opening of the fixing bracket 200. Figure 5 As shown in B and 6B, the front end 411 of the locking button 410 passes sequentially through the vertical opening slot 311 and the horizontal opening slot 312 of the lower anchor 300. Simultaneously, the body 421 of the lifting block 420 is inserted into the vertical opening slot 311 of the lower anchor 300, and the left and right wings 422 of the lifting block 420 contact the upper end of the second tongue plate 310. Therefore, while compressing the first elastic member 430, the lifting block 420 is lifted, and simultaneously, the front end 411 of the locking button 410 contacts the horizontal opening slot 312, and the locking button 410 is also lifted.

[0090] like Figure 5 As shown in C and 6C, when the lifting block 420 is lifted, the interference between the blocking block 413 of the locking button 410 and the lifting block 420 is released, causing the locking button 410 to move forward under the pressure of the second elastic member 440. During this process, the blocking block 413 of the locking button 410 is accommodated in the receiving groove 424 formed on the lower surface of the body 421 of the lifting block 420, and the rear end 412 of the locking button 410 enters the horizontal opening groove 312.

[0091] When the rear end 412 of the locking button 410 enters the horizontal opening slot 312, the locking bracket 200, the second tongue plate 310 and the lower anchor 300 engage and lock. When the operator stops the downward movement of the locking bracket 200, the first elastic member 430, which is in a compressed state, extends and recovers, causing the fixed bracket 200 to rise. During this process, the support member 450 is located behind the locking button 410.

[0092] Therefore, the backward movement of the locking button 410 is restricted, while the locked state remains stable.

[0093] like Figure 7 As shown in Figure a, when the operator wants to detach the webbing W from the lower anchor 300, the cover 201 is used to move the fixing bracket 200 downwards, as shown in Figure a. Figure 7 As shown in b, the lifting block 420 is pushed upward and downward to the anchor 300 while compressing the first elastic member 430. At the same time, the locking button 410 is also pushed upward because the rear end 412 of the locking button 410 contacts the horizontal opening groove 312.

[0094] During this process, the locking button 410 and the lifting block 420 are spaced apart from each other, causing the blocking block 413 of the locking button 410 to disengage from the receiving groove 424 of the lifting block 420. In addition, since the locking button 410 is located on the upper side of the support member 450, the backward movement restriction imposed by the support member 450 is released.

[0095] At this time, the operator presses the front end 411 of the locking button 410, forcing the locking button 410 to move backward, as... Figure 7 As shown in Figure C, as the rear end 412 of the locking button 410 moves away from the horizontal opening groove 312 of the lower anchor 300, the front end 411 of the locking button 410 enters the horizontal opening groove 312, and as the fixed bracket 200 and the second tongue plate 310 disengage, the locking state is released.

[0096] During this process, as the second elastic member 440 undergoes elastic deformation, the rear end 412 of the locking button 410 is pressed forward. In this state, when the operator stops moving the lower part of the fixed bracket 200, the first elastic member 430, which is in a compressed state, extends and recovers, the lifting block 420 descends to press the upper end of the locking button 410 tightly, the blocking block 413 is supported by the body 421 of the descending lifting block 420, and the support member 450 supports the rear end 412 of the locking button 410 from below.

[0097] Therefore, the locking button 410 maintains a stable horizontal position while preventing forward movement, and remains stable in the unlocked state.

[0098] In this state, when the operator uses the cover 201 to move the fixed bracket 200 upward, the front end 411 of the locking button 410 passes through the horizontal opening slot 312 and the vertical opening slot 311 in sequence, causing the fixed bracket 200 to separate from the second tongue plate 310 and the lower anchor 300, as shown. Figure 7 As shown in D.

[0099] As described above, according to the vehicle seat belt connection device of the present invention, the webbing W can be easily and conveniently connected to the lower anchor 300 by simply inserting the fixing bracket 200 fixed to the end of the webbing W into the lower anchor 300. Not only can the webbing W be easily and conveniently separated from the lower anchor 300 by simply pressing the locking button 410 backward, but stability is also ensured because the webbing W will not separate from the lower anchor 300 unless the locking button 410 is pressed.

[0100] Although preferred embodiments of the invention have been shown and described above with reference to the accompanying drawings, various modifications and alterations may be made without departing from the spirit or scope of the invention as defined by the following claims, and these modifications and alterations are also intended to be included within the scope of the invention.
