Description

[Technical field]

[0001] The present invention relates to a side impact protection block and a child seat equipped with a side impact protection block. [Background technology]

[0002] A child car seat is a device placed on a seat of a vehicle to protect an infant, and restrains the infant with a restraining device. In the event of emergency braking or an accidental collision of the vehicle, the child car seat reduces the impact on the infant through the housing, and limits the infant's body movement through the restraining device, reducing the possibility of the infant being injured in an accident and ensuring the safety of the infant during the ride.

[0003] Typically, a side impact protection structure protrudes laterally from the side of a child car seat. In the event of a side impact with a vehicle, the side impact protection structure provided on the sides and lateral sides of the child car seat reduces the impact through a cushioning effect, protecting the body and head of the baby laterally. However, providing a side impact protection structure on the side can take up a relatively large lateral space, which makes it inconvenient to store the child car seat. Summary of the Invention

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

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

[0025] A child seat 200 according to the present application will be generally described with reference to Figs. 1 to 3. 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 being configured to be fixed to a vehicle, such as an automobile, and the seat 230 being for a child to sit on. Each side of the child seat 200 is provided with a mounting seat 210. The side impact protection block 100 may be inserted into either mounting seat 210 so as to be attached to the child seat 200. Of course, two side impact protection blocks 100 may be inserted into the mounting seats 210 on both sides, respectively. However, in normal use, the side impact protection block 100 is inserted only into the side of the child seat 200 that is closer to the inner wall of the vehicle. When the side impact protection block 100 is not needed, the side impact protection block 100 may be removed from the seat, as will be described in detail below.

[0026] In the present embodiment, the side impact protection block 100 is inserted into the seat mounting seat 210 at a generally perpendicular angle 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 oblique angle to the side of the seat.

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

[0028] The side impact protection block 100 includes a housing 110, a slider 120, and an engagement member 130. The housing 110 at least partially accommodates other components of the side impact protection block 100. The side impact protection block 100 is fixed to the seat by a form fit between the housing 110 and a mounting seat 210 of the seat. The slider 120 is slidably disposed within the housing 110, and a user operates the slider 120 to move the engagement member 130 within the housing 110. The side impact protection block 100 is locked to the seat or released from the seat by the engagement member 130. The side impact protection block 100 may further include an elastic member 140 for returning the slider 120.

[0029] More specifically, the housing 110 may have a substantially rectangular shape. The housing 110 has an insert portion 111 at a first housing end (insertion end) of the housing along its longitudinal direction, i.e., a first direction (specifically, the longitudinal direction of the side impact protection block 100), and a second end (free end) of the housing opposite to the first housing end of the housing along the longitudinal direction is configured to abut against a vehicle, e.g., an automobile. The insert portion 111 is form-fitted into the mounting seat 210. In one embodiment, the insert portion 111 has a rectangular cross section, and two opposing side walls are respectively 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 insert portion 111 may have other shapes, for example, a triangular or trapezoidal cross section, as long as it can form-fit with the mounting seat 210. The engagement holes 113 may be formed on one or more side surfaces of the insert portion 111, and the engagement members 130 may be disposed in each engagement hole 113, respectively. In this embodiment, the engagement holes 113 are offset in the vertical direction, however, the present application is not limited thereto, and in other embodiments, the engagement holes 113 may be aligned in the vertical 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 an elastic member receiving portion protruding inward in the lateral direction, i.e., the second direction, is provided within the passage. The block 115 is configured to limit 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 function of the block 115, a slide rail can 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 being longitudinal and transverse, but it should be understood that the first and second directions are not necessarily perpendicular to each other and may intersect at an angle. In one embodiment, the first direction is generally perpendicular to the side of the seat 230, and the second direction is generally parallel to the side of the seat 230. In other embodiments, the first and second directions may each be inclined relative to the side of the seat 230.

[0032] As shown in FIGS. 8-9, a first opening (ie, 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 accommodated within the housing 110 and can be operated from outside the housing 110 to slide along the longitudinal direction of the housing 110. The slider 120 has a generally rectangular shape and has a first slider end engaged with the engagement member 130 along the longitudinal direction 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 ends close to the seat, and the second slider end and the second end of the housing are ends far from the seat. The second slider end is provided with a pressing portion 123, which allows a user to operate the slider 120 through a first opening at the second end of the housing.

[0034] As shown in Figs. 8 and 9, the slider 120 includes an abutment portion 121 and a receding portion 122 adjacent to each other along the longitudinal direction at a first slider end, and the abutment portion 121 is closer to the end of the first slider end than the receding portion 122. As the slider 120 slides, the abutment portion 121 or the receding portion 122 can correspond to the position of the engagement hole 113. The lateral dimension of the abutment portion 121 is set so that, when the abutment portion 121 is at a position corresponding to the engagement hole 113, the engagement member 130 is pushed to protrude to the locked position. The lateral dimension of the receding portion 122 is set so that, when the abutment portion 121 is at a position corresponding to the engagement hole 113, the engagement member 130 is allowed to recede to the released position.

[0035] The elastic member 140 acts between the housing 110 and the slider 120 to bias the slider 120 toward the second slider end. The second slider end is provided with an elastic member abutment portion that protrudes outward in the lateral direction. The elastic member 140 is disposed between the elastic member accommodating portion and the elastic member abutment portion.

[0036] In this embodiment, the position of the slider 120 away from the seat corresponds to the lock position of the engagement member 130, and the position of the slider 120 close to the seat corresponds to the release position of the engagement member 130. When the engagement member 130 is in the lock position, the slider 120 pushes the engagement member 130 along the second direction. Therefore, the operation of releasing the side impact protection block 100 moves the slider 120 toward the seat. That is, the slider 120 slides toward the first slider end along the longitudinal direction, thereby moving the engagement member 130 from the lock position to the release position. However, the unlocking direction of the slider 120 is not limited thereto. In other embodiments, the operation of releasing the side impact protection block 100 may also move the slider 120 away from the seat. That is, the slider 120 slides toward the second slider end along the longitudinal direction, thereby moving the engagement member 130 from the lock position to the release position. In such an embodiment, the recess 122 is closer to the end of the first slider end than the abutment portion 121, an opening is provided in the side of the housing 110 for a 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 accommodated in the housing 110, is disposed at a vertical position of 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 an unlocked position where it retracts into the housing 110. The slider 120 slides along the vertical direction to drive the engaging member 130 to move between the locked position and the unlocked position.

[0038] In this embodiment, the sliding direction (vertical direction) of the slider 120 is approximately perpendicular to the moving direction (horizontal direction) of the engagement member 130. However, the present application is not limited to this. In other embodiments, the sliding direction of the slider 120 may be inclined with respect to the moving direction of the engagement member 130, and the two may be approximately intersecting each other.

[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 only partially exposed to the outside of the housing 110 by the engaging hole 113, but cannot move through the engaging hole 113. Due to the advantage of the symmetry of the spherical shape, the engaging member 130 does not need to be arranged along a specific direction, and therefore can roll arbitrarily when contacting with the slider 120. In addition, the spherical engaging member 130 is beneficial to reduce friction between the slider 120 and the housing 110. However, the present application is not limited thereto, and in other embodiments, the engaging member 130 may have other shapes, such as a cylindrical shape or a wedge shape.

[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 abutment portion 121 of the slider 120 may be wrapped by or made of a metal reinforcement material, the outer surface of the insert portion 111 of the housing 110 may be wrapped by or made of a metal reinforcement sheet, and the engagement member 130 may be a metal ball.

[0041] As shown in FIGS. 6 to 7, each mounting seat 210 is recessed inwardly of the seat along the vertical direction so that the insertion portion 111 of the side impact protection block 100 is inserted into the mounting seat 210.

[0042] An engagement groove 211 recessed laterally is provided on the inner wall of the recess in a position adjacent to the open end of the recess of the mounting seat 210. The position of the engagement groove 211 is provided corresponding to the position of the engagement member 130. The dimensions of the open end are set as follows, and 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 open 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 retreat into the housing 110 and disengage from the stop at the open end.

[0043] All or part 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 is provided on the side where the open end of the mounting seat 210 stops the engaging member 130 in the locked position.

[0044] 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 engagement member 130 in a direction perpendicular to the first direction to the overall cross-sectional area S of the side impact protection block 100 in a direction perpendicular to the first direction is greater than 1:45. The appropriate dimension of the cross-sectional area S2 of the engagement member 130 helps the side impact protection block 100 to stably engage with the child seat 200.

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

[0046] The installation and removal operations of the side impact protection block 100 according to the first embodiment of the present application will now be described.

[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. At the same time, 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 of the mounting seat 210, so that the movement of the side impact protection block 100 relative to the mounting seat 210 is not hindered. After the side impact protection block 100 is completely inserted into the mounting seat 210, the user no longer presses the slider 120, so that the slider 120 returns to the second slider end (lock position) under the force of the elastic member 140. At this time, the abutment 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 impact protection block 100 and the mounting seat 210.

[0048] It should be noted that if the side impact protection block 100 is not fully inserted into the mounting seat 210, the engagement member 130 cannot be aligned with the engagement groove 211, and therefore cannot move into the engagement groove 211 and cannot move to the locked position. In this case, the engagement member 130 abuts against the transition portion between the retreating portion 122 and the abutting portion 121 of the slider 120, and does not allow the abutting portion 121 of the slider 120 to move to the position of the engagement hole 113. Thus, the slider 120 cannot return completely. The user can sense that the slider 120 is "stuck", and thereby know that the side impact protection block 100 is not inserted in the fixed position. Thus, the side impact protection block 100 of the present application provides a warning function for incomplete insertion, improving 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 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. At the same time, 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 of the mounting seat 210, so that the movement of the side impact protection block 100 relative to the mounting seat 210 is not hindered. After the side impact protection block 100 is completely removed, the user no longer presses the slider 120, so that the slider 120 returns to the second slider end (lock position) under the bias of the elastic member 140. At this time, the abutting portion 121 of the slider 120 corresponds to the position of the engaging hole 113, and the engaging member 130 returns to the lock position.

[0050] A side impact protection block 100 according to a second embodiment of the present application will be described with reference to FIGS.

[0051] The side impact protection block 100 of the second embodiment is almost the same as that of the first embodiment, except for the operation method of the slider 120. Therefore, the description of the common points between the two embodiments will be omitted.

[0052] In the second embodiment, the side impact protection block 100 further includes a button 150. The housing 110 is provided with a second opening (i.e., a lateral opening) on ​​its side wall and at the second slider end, and the button 150 is provided movably in the second opening in a lateral direction relative to the housing 110, allowing the button 150 to be pressed from 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 provided 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 the present application, the second slider end is provided with a slider ramp 124, and the button 150 is provided with a button ramp 151, which abuts against the slider ramp 124 to convert the lateral movement of the button 150 into the vertical movement of the slider 120. However, the present application is not limited thereto, and the button 150 may be engaged with the slider 120 in other ways.

[0054] In view of the above, the present application provides a side impact protection block that can be conveniently attached to or detached from a seat and can provide a locking function for the seat. The side impact protection block of the present application is a detachable side impact protection block that can be selectively attached according to a user's requirements. Furthermore, the side impact protection block of the present application provides an incomplete insertion warning function so that the user is aware that the side impact protection block is not properly attached to the seat.

[0055] While preferred embodiments have been shown and described herein, it is to be understood that these embodiments are given by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the spirit of the disclosure. It is therefore intended that the appended claims cover all such variations as come within the spirit and scope of the disclosure. [Explanation of symbols]
