Description

Technical Field

[0001] The present invention relates to a side collision protection block and a child seat including the side collision protection block.

Background Art

[0002] A child seat is a device that is placed on an automobile seat to protect an infant and restrains the infant by a restraint device. In the case of an emergency brake or an accidental collision of an automobile, the child seat reduces the impact on the infant by a housing, restricts the movement of the infant's body by the restraint device, reduces the possibility that the infant is injured in an accident, and ensures the safety of the infant during riding.

[0003] Normally, a side collision protection structure protrudes laterally from the side of a child seat. When the automobile collides sidewise, the impact is reduced through a buffering effect by the side and the side collision protection structure provided on the side of the child seat, and the body and head of the infant are protected laterally. However, providing a side collision protection structure on the side may occupy a relatively large lateral space, which is inconvenient for storing the child seat.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Although the present disclosure is shown and described herein with reference to particular embodiments, the present disclosure should not be limited to the details shown. Rather, various modifications may be made to these details without departing from the scope of the equivalents of the claims.

[0024] The descriptions of "front", "rear", "upper", and "lower" in this specification are for convenience of understanding only, and the present disclosure is not limited to these directions and can be adjusted according to the actual situation. Although this application is described with reference to an enumeration of typical embodiments, the terms used are illustrative and exemplary, not limiting.

[0025] Referring to FIGS. 1 to 3, the child seat 200 according to the present application will be described in its entirety. FIGS. 1 and 2 show rear perspective views of the child seat 200. As can be seen from the drawings, the child seat 200 includes a base 220 and a seat 230. The base 220 is configured to be fixed to a vehicle, for example, an automobile, and the seat 230 is for a child to sit on. Mounting seats 210 are provided on each side of the child seat 200. The side collision protection block 100 may be inserted into any one of the mounting seats 210 so as to be attached to the child seat 200. Of course, the two side collision protection blocks 100 may be inserted into the mounting seats 210 on both sides respectively. However, in normal use, the side collision protection block 100 is inserted only on the side closer to the inner wall of the vehicle of the child seat 200. When the side collision protection block 100 is not required, the side collision protection block 100 may be removed from the seat as will be described in detail below.

[0026] In the embodiment of this application, the side impact protection block 100 is inserted into the seat mounting seat 210 at an angle substantially perpendicular to the side of the seat. However, in other embodiments, the side impact protection block 100 may be inserted into the mounting seat 210 at an angle inclined with respect to the side of the seat.

[0027] The structure of the side impact protection block 100 according to the first embodiment of this application and the matching mounting seat 210 will be described with reference to Figures 4 to 9.

[0028] The side impact protection block 100 includes a housing 110, a slider 120, and an engaging member 130. The housing 110 at least partially accommodates the other components of the side impact protection block 100. The side impact protection block 100 is secured to the seat by a geometric fit between the housing 110 and the seat mounting seat 210. The slider 120 is slidably positioned within the housing 110, and the user moves the engaging member 130 within the housing 110 by operating the slider 120. The side impact protection block 100 is locked to or released from the seat by the engaging member 130. The side impact protection block 100 may further include an elastic member 140 for returning the slider 120 to its original position.

[0029] More specifically, the housing 110 may be substantially rectangular in shape. The housing 110 has an insertion portion 111 at a first housing end (insertion end) of the housing along its longitudinal direction, i.e., the first direction (specifically, the longitudinal direction of the side impact protection block 100), and the second end (free end) of the housing, opposite the first housing end along the longitudinal direction, is configured to abut against a vehicle, such as an automobile. The insertion portion 111 is fitted into the mounting seat 210. In one embodiment, the insertion portion 111 has a rectangular cross-section, and two opposing side walls are provided with engagement holes 113 that are offset along the longitudinal direction, and an engagement member 130 is disposed in each engagement hole 113. In other embodiments, the insertion portion 111 may have other shapes, for example, a triangular or trapezoidal cross-section, as long as it can be fitted into the mounting seat 210. The engagement holes 113 may be formed on one or more sides of the insertion portion 111, and the engagement member 130 may be disposed in each engagement hole 113. In this embodiment, the multiple engagement holes 113 are offset along the longitudinal direction. However, this application is not limited thereto, and in other embodiments, the multiple engagement holes 113 may be aligned along the longitudinal direction.

[0030] In one embodiment, the housing 110 includes a block 115 provided around the slider 120. The block 115 is provided with a passage for the vertical movement of the slider 120, and within the passage is provided an elastic member housing that protrudes inward in the lateral direction, i.e., a second direction. The block 115 is configured to restrict the sliding direction of the slider 120 and reduce frictional resistance between the slider 120 and the housing 110. In another embodiment, instead of the role of the block 115, a slide rail may be provided inside the housing 110.

[0031] In this application, the first and second directions of the side impact protection block 100 are described as the longitudinal and transverse directions, but it should be understood that the first and second directions do not necessarily have to be perpendicular to each other and may intersect at an angle. In one embodiment, the first direction is substantially perpendicular to the side of the sheet 230, and the second direction is substantially parallel to the side of the sheet 230. In other embodiments, the first and second directions may each be inclined with respect to the side of the sheet 230.

[0032] As shown in Figures 8 and 9, a first opening (i.e., a vertical opening) is provided at the second end of the housing, allowing the slider 120 to be pushed from the outside through the first opening.

[0033] The slider 120 is at least partially housed within the housing 110 and is operated from outside the housing 110 to slide along the longitudinal direction of the housing 110. The slider 120 has a substantially rectangular shape and, along its longitudinal direction, has a first slider end that engages with an engaging member 130 and a second slider end for external operation. It should be understood that the first slider end and the first housing end of the housing are the ends closer to the seat, and the second slider end and the second housing end are the ends further away from the seat. A pressing portion 123 is provided at the second slider end, which allows the user to operate the slider 120 through a first opening at the second end of the housing.

[0034] As shown in Figures 8 and 9, the slider 120 includes a contact portion 121 and a retracted portion 122 adjacent to each other in the longitudinal direction at the first slider end, with the contact portion 121 being closer to the end of the first slider end than the retracted portion 122. As the slider 120 slides, the contact portion 121 or the retracted portion 122 can correspond to the position of the engagement hole 113. The lateral dimension of the contact portion 121 is such that, when it is in the position corresponding to the engagement hole 113, the engagement member 130 is pushed and protrudes to the locked position. The lateral dimension of the retracted portion 122 is such that, when it is in the position corresponding to the engagement hole 113, the engagement member 130 is allowed to retract to the released position.

[0035] The elastic member 140 acts between the housing 110 and the slider 120, biasing the slider 120 toward the second slider end. The second slider end is provided with an elastic member contact portion that protrudes laterally outward. The elastic member 140 is positioned between the elastic member housing portion and the elastic member contact portion.

[0036] In this embodiment, the position of the slider 120 away from the seat corresponds to the locked position of the engaging member 130, and the position of the slider 120 closer to the seat corresponds to the released position of the engaging member 130. When the engaging member 130 is in the locked position, the slider 120 pushes the engaging member 130 along the second direction. Therefore, the operation to release the side impact protection block 100 moves the slider 120 toward the seat. That is, the slider 120 slides longitudinally toward the first slider end, moving the engaging member 130 from the locked position to the released position. However, the direction of unlocking the slider 120 is not limited to this. In other embodiments, the operation to release the side impact protection block 100 may also move the slider 120 away from the seat. That is, the slider 120 slides longitudinally toward the second slider end, moving the engaging member 130 from the locked position to the released position. In such an embodiment, the retraction portion 122 is closer to the end of the first slider end than the contact portion 121, the opening is provided on the side of the housing 110 to allow the user to move the slider 120 away from the seat, and the elastic member 140 biases the slider 120 toward the first slider end.

[0037] The engaging member 130 is housed within the housing 110, positioned longitudinally within the housing 110, and can move along the lateral direction of the housing 110 between a locked position where it protrudes from the housing 110 and a released position where it retracts into the housing 110. The slider 120 drives the engaging member 130 to move between the locked and released positions by sliding along the longitudinal direction.

[0038] In this embodiment, the sliding direction (vertical direction) of the slider 120 is substantially perpendicular to the movement direction (lateral direction) of the engaging member 130. However, this application is not limited thereto. In other embodiments, the sliding direction of the slider 120 may be inclined with respect to the movement direction of the engaging member 130, and the two may intersect substantially.

[0039] In this embodiment, the engaging member 130 is spherical, and in the housing 110, the diameter of the engaging hole 113 is smaller than the spherical diameter of the engaging member 130. In this way, the engaging member 130 can be partially exposed to the outside of the housing 110 through the engaging hole 113, but it cannot move through the engaging hole 113. Due to the advantage of the spherical symmetry, the engaging member 130 does not need to be positioned along a particular direction and can therefore roll arbitrarily when in contact with the slider 120. Furthermore, the spherical engaging member 130 is beneficial in reducing friction between the slider 120 and the housing 110. However, this application is not limited thereto, and in other embodiments, the engaging member 130 may have other shapes, such as cylindrical or wedge-shaped.

[0040] All or some of the various components of the side impact protection block 100 may be provided as metal components to improve the performance of the side impact protection block 100. For example, the contact portion 121 of the slider 120 may be wrapped with a metal reinforcement or made of a metal reinforcement. The outer surface of the insertion portion 111 of the housing 110 may be wrapped with a metal reinforcement sheet or made of a metal reinforcement sheet, and the engaging member 130 may be a metal ball.

[0041] As shown in Figures 6 and 7, each mounting seat 210 is recessed inward along the longitudinal direction towards the inside of the seat so that the insertion portion 111 of the side impact protection block 100 is inserted into and positioned within the mounting seat 210.

[0042] A laterally recessed engagement groove 211 is provided on the inner wall of the recess of the mounting seat 210, near the opening end of the recess. The position of the engagement groove 211 corresponds to the position of the engagement member 130. The dimensions of the opening end are set as follows: When the engagement member 130 is in its locked position, the engagement member 130 is inserted into the engagement groove 211 and stopped at the opening end, thereby fixing the side impact protection block 100 to the seat; and when the engagement member 130 is in the released position, the engagement member 130 can retract into the housing 110 and disengage from the stop at the opening end.

[0043] Some or all of the components of the mounting seat 210 may be replaced with metal components to improve the performance of the mounting seat 210. For example, a metal reinforcing sheet may be provided on the side where the open end of the mounting seat 210 locks the engaging member 130 in the locked position.

[0044] Referring to Figures 5 and 8, in one embodiment, the ratio of the overall width W of the side impact protection block 100 in the second direction to the overall length L in the first direction may be between 1:4 and 1:5. The ratio of the overall width W of the side impact protection block 100 to the overall thickness H of the side impact protection block 100 may be between 1:1.5 and 1:2. The ratio of the cross-sectional area S2 of the engaging member 130 in the direction perpendicular to the first direction to the overall cross-sectional area S of the side impact protection block 100 in the direction perpendicular to the first direction is greater than 1:45. Appropriate dimensions of the cross-sectional area S2 of the engaging member 130 help to securely engage the side impact protection block 100 with the child seat 200.

[0045] The ratio of the length L1 of the insertion portion 111 in the first direction to the total length L of the side impact protection block 100 in the first direction may be 1:10 or less. The ratio of the cross-sectional area S1 of the insertion portion 111 in the direction perpendicular to the first direction to the total cross-sectional area S of the side impact protection block 100 in the direction perpendicular to the first direction may be between 1:6 and 1:7.

[0046] The following describes the installation and removal operations of the side impact protection block 100 according to the first embodiment of this application.

[0047] When attaching the side impact protection block 100 to the seat, the user presses the slider 120 toward the first slider end (release position) through the opening of the housing 110. At this time, the retracted portion 122 of the slider 120 corresponds to the position of the engagement hole 113, allowing the engagement member 130 to move to the release position. Simultaneously, the user inserts the side impact protection block 100 into the mounting seat 210. During the insertion process, the engagement member 130 is pressed toward the release position by the inner wall of the recess in the mounting seat 210, so as not to hinder the movement of the side impact protection block 100 relative to the mounting seat 210. After the side impact protection block 100 is fully inserted into the mounting seat 210, the user stops pressing the slider 120, and the slider 120 returns to the second slider end (locked position) under the biasing force of the elastic member 140. At this time, the contact portion 121 of the slider 120 corresponds to the position of the engagement hole 113, and the engagement member 130 is restricted to the locked position. Therefore, the engagement member 130 protrudes from the engagement hole 113 and is inserted into the engagement groove 211 of the mounting seat 210, thereby locking the relative movement between the side collision protection block 100 and the mounting seat 210.

[0048] Furthermore, if the side impact protection block 100 is not fully inserted into the mounting seat 210, the engaging member 130 cannot align with the engaging groove 211, and therefore cannot move into the engaging groove 211 or move to the locked position. In this case, the engaging member 130 abuts against the transition portion between the retracted portion 122 and the contact portion 121 of the slider 120, preventing the contact portion 121 of the slider 120 from moving to the position of the engaging hole 113. Therefore, the slider 120 cannot fully return to its original position. The user can sense that the slider 120 is "stuck," thereby knowing that the side impact protection block 100 is not inserted into its proper position. Therefore, the side impact protection block 100 of this application provides a warning function against incomplete insertion and improves safety performance.

[0049] Similarly, when removing the side impact protection block 100 from the seat, the user presses the slider 120 toward the first slider end (release position) through the opening in the housing 110. At this time, the retracted portion 122 of the slider 120 corresponds to the position of the engagement hole 113, allowing the engagement member 130 to move to the release position. Simultaneously, the user pulls the side impact protection block 100 out of the mounting seat 210. During the pulling process, the engagement member 130 is pressed toward the release position by the inner wall of the recess in the mounting seat 210, and therefore does not hinder the movement of the side impact protection block 100 relative to the mounting seat 210. After the side impact protection block 100 is completely removed, the user no longer presses the slider 120, and the slider 120 returns to the second slider end (locked position) under the biasing force of the elastic member 140. At this time, the contact portion 121 of the slider 120 corresponds to the position of the engagement hole 113, and the engagement member 130 returns to the locked position.

[0050] A side impact protection block 100 according to a second embodiment of this application will be described with reference to Figures 10 to 12.

[0051] The side impact protection block 100 of the second embodiment is almost identical to that of the first embodiment, the only difference being the operating method of the slider 120. Therefore, the similarities between the two embodiments will not be explained.

[0052] In the second embodiment, the side impact protection block 100 further includes a button 150. The housing 110 has a second opening (i.e., a lateral opening) on ​​its side wall and at the second slider end, and the button 150 is mounted so as to be movable laterally in the second opening relative to the housing 110, allowing the button 150 to be pressed from the outside through the second opening. Correspondingly, in this embodiment, the housing 110 does not need to have an opening at the second end of the housing.

[0053] The button 150 is configured such that when a user presses the button 150 from outside the housing 110, the button 150 drives the slider 120 to move to the second slider end (i.e., the release position). In the embodiment of this application, the second slider end is provided with a slider bevel 124, and the button 150 is provided with a button bevel 151, the button bevel 151 which contacts the slider bevel 124, converting the lateral movement of the button 150 into the vertical movement of the slider 120. However, this application is not limited thereto, and the button 150 may engage with the slider 120 in other ways.

[0054] Based on the above, this application provides a side impact protection block that can be conveniently attached to or removed from a seat and can provide a locking function to the seat. The side impact protection block of this application is a removable side impact protection block that can be selectively attached according to the user's requirements. Furthermore, the side impact protection block of this application provides an incomplete insertion warning function so that the user becomes aware when the side impact protection block is not properly attached to the seat.

[0055] While preferred embodiments are shown and described herein, it should be understood that these embodiments are provided for illustrative purposes only. Those skilled in the art will be able to conceive of numerous variations, modifications, and substitutions without departing from the spirit of this disclosure. Accordingly, the appended claims are intended to cover all variations that fall within the spirit and scope of this disclosure. [Explanation of symbols]
