Description

Technical Field

[0001] This invention relates to a side impact protection block and a child safety seat including the side impact protection block. Background Technology

[0002] Child safety seats are devices installed in car seats to protect infants and young children. They use restraint devices to restrain infants and young children. In the event of emergency braking or a collision, the child safety seat uses its shell to cushion the impact on the infant or young child and the restraint devices to restrict the infant's body movement, thereby reducing the chance of injury to the infant or young child in an accident and ensuring the infant's safety while traveling in a car.

[0003] Typically, child safety seats also have side impact protection structures that extend laterally. In the event of a side collision, the side wings of the child safety seat and the side impact protection structures thereon are used to cushion the impact and protect the infant's body and head from the side. However, the side impact protection structures on the side wings take up a lot of lateral space, making it inconvenient to store the child safety seat.

[0004] Therefore, it is necessary to provide a removable side impact protection block so that users can selectively install it according to their needs. Summary of the Invention

[0054] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from the invention.

[0055] The descriptions of directions such as "front", "back", "up" and "down" used in this document are for ease of understanding only. This invention is not limited to these directions, but can be adjusted according to actual circumstances. Although this application has been described with reference to typical embodiments, the terminology used is illustrative and exemplary, and not restrictive.

[0056] Reference Figures 1 to 3 Overall description of the child safety seat 200 according to this application. Figure 1 and Figure 2A perspective view of the rear of the child safety seat 200 is shown. As can be seen, the child safety seat 200 includes a base 220 and a seat 230, where the base 220 is used to secure it to a vehicle (e.g., a car), and the seat 230 is for a child to sit in. Mounting seats 210 are provided on both sides of the child safety seat 200. A side impact protection block 100 can be inserted into either mounting seat 210 for installation into the child safety seat 200. Alternatively, both side impact protection blocks 100 can be inserted into the mounting seats 210 on each side. However, in normal use, the side impact protection block 100 is only inserted on the side of the child safety seat 200 closest to the vehicle's inner wall. When the side impact protection block 100 is not needed, it can be removed from the seat, as detailed below.

[0057] In the embodiments of this application, the side impact protection block 100 is inserted into the seat mounting base 210 at an angle substantially perpendicular to the side of the seat. However, in other embodiments, the side impact protection block 100 may also be inserted into the mounting base 210 at an angle inclined to the side of the seat.

[0058] Reference Figures 4 to 9 The structure of the side impact protection block 100 according to the first embodiment of this application and the mounting base 210 therewith are described.

[0059] The side impact protection block 100 includes a housing 110, a slider 120, and a locking member 130. The housing 110 at least partially houses the other components of the side impact protection block 100. A form-fit between the housing 110 and the seat mounting base 210 secures the side impact protection block 100 to the seat. The slider 120 is slidably disposed within the housing 110, and the user moves the locking member 130 within the housing 110 by operating the slider 120. The locking member 130 locks the side impact protection block 100 to or releases it from the seat. The side impact protection block 100 may also include a resilient member 140 for resetting the slider 120.

[0060] More specifically, the housing 110 may be generally rectangular. The housing 110 has an insertion portion 111 at a first end (insertion end) along its longitudinal direction (i.e., the first direction), and a second end (free end) opposite the first end along the longitudinal direction for abutting against a vehicle (e.g., a car). The insertion portion 111 is shaped-fitted into the mounting base 210. In one embodiment, the insertion portion 111 has a rectangular cross-section and longitudinally offset engaging holes 113 are formed on two opposite sidewalls, with engaging members 130 provided at each engaging hole 113. In other embodiments, the insertion portion 111 may have other shapes, such as a triangular or trapezoidal cross-section, as long as it can form a shape fit with the mounting base 210. Engaging holes 113 may be formed on one or more sides of the insertion portion 111, and engaging members 130 may be provided at each engaging hole 113. In this embodiment, multiple engaging holes 113 are longitudinally offset. However, this application is not limited to this. In other embodiments, the plurality of engagement holes 113 may be aligned longitudinally.

[0061] In one embodiment, the housing 110 includes a block 115 disposed around the slider 120. The block 115 has a channel for longitudinal movement of the slider 120, and within the channel is a laterally (i.e., in a second direction) inwardly projecting elastic element housing. The block 115 serves to define the sliding direction of the slider 120 and reduce the frictional resistance between the slider 120 and the housing 110. In other embodiments, a slide rail may be disposed inside the housing 110 to replace the function of the block 115.

[0062] Although the first and second directions of the side impact protection block 100 are described in this application as longitudinal and lateral, it should be understood that the first and second directions need not be perpendicular to each other, but may intersect at an angle. In one embodiment, the first direction is substantially perpendicular to the side of the seat 230, and the second direction is substantially parallel to the side of the seat 230. In other embodiments, the first and second directions may be inclined to the side of the seat 230, respectively.

[0063] like Figures 8 to 9 As shown, a longitudinal opening is provided at the second end of the housing to allow the slider 120 to be pushed from the outside through the longitudinal opening.

[0064] The slider 120 is at least partially housed within the housing 110 and is operable from outside the housing 110, sliding longitudinally along the housing 110. The slider 120 is generally rectangular, having a first end longitudinally engaged with the engaging member 130 and a second end longitudinally operable from the outside. It should be understood that the first end of the slider and the first end of the housing are located closer to the seat, while the second end of the slider and the second end of the housing are located farther from the seat. A pressing portion 123 is provided at the second end of the slider to allow the user to operate the slider 120 through a longitudinal opening at the second end of the housing.

[0065] like Figures 8 to 9 As shown, the slider 120 includes a longitudinally adjacent abutment 121 and a retractable portion 122 at its first end, with the abutment 121 being closer to the end of the first end of the slider than the retractable portion 122. As the slider 120 slides, either the abutment 121 or the retractable portion 122 can correspond to the position of the engaging hole 113. The lateral dimension of the abutment 121 is configured such that, when it is in the position corresponding to the engaging hole 113, it pushes the engaging member 130 to extend into the locked position. The lateral dimension of the retractable portion 122 is configured such that, when it is in the position corresponding to the engaging hole 113, it allows the engaging member 130 to retract to the released position.

[0066] The elastic element 140 acts between the housing 110 and the slider 120 to bias the slider 120 toward the second end of the slider. A laterally outwardly protruding elastic element engaging portion is provided at the second end of the slider. The elastic element 140 is disposed between the elastic element mounting portion and the elastic element engaging portion.

[0067] In this embodiment, the position of slider 120 away from the seat corresponds to the locked position of latching member 130, and the position of slider 120 near the seat corresponds to the released position of latching member 130. Therefore, releasing the side impact protection block 100 involves moving slider 120 toward the seat. That is, the sliding of slider 120 longitudinally toward the first end of slider causes latching member 130 to move from the locked position to the released position. However, the unlocking direction of slider 120 is not limited to this. In other embodiments, releasing the side impact protection block 100 can also involve moving slider 120 away from the seat. That is, the sliding of slider 120 longitudinally toward the second end of slider causes latching member 130 to move from the locked position to the released position. In such an embodiment, the retracting portion 122 is closer to the end of the first end of slider than the abutting portion 121, the opening is provided on the side of housing 110 so that the user can move slider 120 away from the seat, and the elastic member 140 biases slider 120 toward the first end of slider.

[0068] The engaging member 130 is housed in the housing 110, positioned at a longitudinal position within the housing 110, and is movable along the lateral side of the housing 110 between a locked position extending out of the housing 110 and a released position retracted from the housing 110. The sliding of the slider 120 along the longitudinal direction causes the engaging member 130 to move between the locked and released positions.

[0069] In this embodiment, the sliding direction (longitudinal) of the slider 120 is approximately perpendicular to the moving direction (lateral) of the engaging member 130. However, this application is not limited to this. In other embodiments, the sliding direction of the slider 120 may be inclined to the moving direction of the engaging member 130, and the two only need to approximately intersect.

[0070] In this embodiment, the engaging member 130 is spherical, and the diameter of the engaging hole 113 in the housing 110 is smaller than the diameter of the ball of the engaging member 130. Thus, the engaging member 130 can only be partially exposed to the outside of the housing 110 through the engaging hole 113, and cannot move through the engaging hole 113. Thanks to the symmetry of the sphere, the engaging member 130 does not need to be positioned in a specific direction, and therefore can roll freely upon contact with the slider 120. Furthermore, the spherical shape of the engaging member 130 helps reduce friction between it and the slider 120 and the housing 110. However, this application is not limited to this; in other embodiments, the engaging member 130 can be other shapes, such as cylindrical or wedge-shaped.

[0071] All or part of the components of the side impact protection block 100 can be made of metal to improve the performance of the side impact protection block 100. For example, the abutment portion 121 of the slider 120 can be covered with or made of a metal reinforcement. The outer surface of the insertion portion 111 of the housing 110 can be covered with or made of a metal reinforcement sheet. The engaging member 130 can be a metal ball.

[0072] like Figures 6 to 7 As shown, each mounting base 210 is recessed longitudinally toward the interior of the seat so that the insertion portion 111 of the side impact protection block 100 is inserted into and positioned in the mounting base 210.

[0073] At the opening end of the recessed portion near the mounting base 210, and on the inner wall of the recessed portion, a transversely recessed engaging groove 211 is provided. The position of the engaging groove 211 corresponds to the position of the engaging member 130, wherein the size of the opening end is set such that when the engaging member 130 is in its locked position, the engaging member 130 is inserted into the engaging groove 211 and stopped at the opening end, thereby fixing the side impact protection block 100 to the seat; when the engaging member 130 is in the released position, the engaging member 130 retracts into the housing 110 and can disengage from the stop at the opening end.

[0074] All or part of the components of the mounting base 210 can be replaced with metal components to improve the performance of the mounting base 210. For example, a metal reinforcing plate is provided on one side of the open end stop engagement member 130 of the mounting base 210 in the locking position.

[0075] See Figure 5 and Figure 8In one embodiment, the ratio of the overall width W of the side impact protection block 100 in the second direction to its overall length L in the first direction can be between 1:4 and 1:5. The ratio of the overall width W of the insertion portion 111 to its overall thickness H can be between 1:1.5 and 1:2. The ratio of the cross-sectional area S2 of the engaging member 130 in the perpendicular direction to the overall cross-sectional area S of the side impact protection block 100 in the perpendicular direction is greater than 1:45. Appropriate dimensions of the cross-sectional area S2 of the engaging member 130 facilitate stable engagement of the side impact protection block 100 with the child safety seat 200.

[0076] The ratio of the length L1 of the insertion part 111 in the first direction to the overall length L of the side impact protection block 100 in the first direction can be less than or equal to 1:10. The ratio of the cross-sectional area S1 of the insertion part 111 in the first direction to the overall cross-sectional area S of the side impact protection block 100 in the first direction can be between 1:6 and 1:7.

[0077] The installation and removal operations of the side impact protection block 100 according to the first embodiment of this application will now be described.

[0078] When installing the side impact protection block 100 onto the seat, the user pushes the slider 120 towards its first end (release position) through the opening in the housing 110. At this time, the retracting portion 122 of the slider 120 corresponds to the position of the engaging hole 113, allowing the engaging member 130 to move to the release position. Simultaneously, the user inserts the side impact protection block 100 into the mounting base 210. During insertion, the engaging member 130 is pressed towards the release position by the inner wall of the recess in the mounting base 210, thus not hindering the movement of the side impact protection block 100 relative to the mounting base 210. After the side impact protection block 100 is fully inserted into the mounting base 210, the user stops pushing the slider 120, so the slider 120 returns to its second end (locked position) under the bias of the elastic member 140. At this time, the pushing portion of the slider 120 corresponds to the position of the engaging hole 113, limiting the engaging member 130 to the locked position. Therefore, the engaging member 130 extends from the engaging hole 113 and inserts into the engaging groove 211 of the mounting base 210, thereby locking the relative movement between the side impact protection block 100 and the mounting base 210.

[0079] It should be understood that if the side impact protection block 100 is not fully inserted into the mounting base 210, the engaging member 130 cannot align with the engaging slot 211, and therefore cannot move into the engaging slot 211, and thus cannot move to the locked position. In this case, the engaging member 130 abuts against the transition portion between the retracting portion 122 and the abutting portion 121 of the slider 120, preventing the abutting portion 121 of the slider 120 from moving to the position of the engaging hole 113. Therefore, the slider 120 cannot be fully reset. The user can perceive that the slider 120 is "stuck," thus knowing that the side impact protection block 100 has not been inserted into place. Therefore, the side impact protection block 100 of this application provides a warning function for incomplete insertion, improving safety performance.

[0080] When removing the side impact protection block 100 from the seat, the user similarly pushes the slider 120 towards its first end (release position) through the opening in the housing 110. At this time, the retracting portion 122 of the slider 120 corresponds to the position of the engaging hole 113, allowing the engaging member 130 to move to the release position. Simultaneously, the user pulls the side impact protection block 100 out of the mounting base 210. During the pulling process, the engaging member 130 is pressed towards the release position by the inner wall of the recess in the mounting base 210, thus not hindering the movement of the side impact protection block 100 relative to the mounting base 210. After the side impact protection block 100 is completely removed, the user no longer pushes the slider 120, so the slider 120 returns to its second end (locked position) under the bias of the elastic member 140. At this time, the pushing portion of the slider 120 corresponds to the position of the engaging hole 113, causing the engaging member 130 to return to the locked position.

[0081] Now refer to Figures 10 to 12 A side impact protection block 100 according to a second embodiment of this application is described.

[0082] The side impact protection block 100 in the second embodiment is largely the same as that in the first embodiment, except that the operation of the slider 120 is different. Therefore, the similarities between the two will not be described again.

[0083] In the second embodiment, the side impact protection block 100 also includes a button 150. The housing 110 has a lateral opening on its side wall and at the second end of the slider. The button 150 is laterally movable relative to the housing 110 at the lateral opening, allowing the button 150 to be pushed from the outside through the lateral opening. Accordingly, in this embodiment, the housing 110 does not need to have an opening at its second end.

[0084] Button 150 is configured such that when a user pushes button 150 from outside housing 110, button 150 causes slider 120 to move towards the second end of slider (i.e., the release position). In this embodiment, slider 150 has a slider ramp 124 at the second end, and button 150 has a button ramp 151. Button ramp 151 abuts against slider ramp 124 to convert the lateral movement of button 150 into the longitudinal movement of slider 120. However, this application is not limited to this; button 150 can also be engaged with slider 120 in other ways.

[0085] In summary, this application provides a side impact protection block that can be easily installed onto or removed from a seat and provides a locking function relative to the seat. Furthermore, the side impact protection block of this application provides a warning function for incomplete insertion, alerting the user that the side impact protection block is not properly installed onto the seat.

[0086] While preferred embodiments have been shown and described herein, it should be understood that these embodiments are given by way of example only. Many variations, modifications, and substitutions will occur to those skilled in the art without departing from the spirit of the invention. Therefore, the appended claims are intended to cover all such variations that fall within the spirit and scope of the invention.
