Description
Technical Field
[0001] The present disclosure relates to a child safety restraint. Background Art
[0002] Child restraints are configured to be installed in a vehicle and may be held in place by a vehicle seat belt that typically has a shoulder section and a leg section. Child safety seats may also be held in place using alternative means, such as a soft latch system having a belt connected to an anchor point built into the vehicle structure. In the event of an accident, the belt or soft latch system will prevent or at least reduce movement of the child restraint relative to the vehicle.
[0003] In some forms, the child restraint is in the form of a child seat that can be installed in a vehicle and held in place by the vehicle seat belts or a soft latch system. In other forms, the child safety seat can be in the form of a child seat that is connected to a seat base that is installed in a vehicle and held in place by the vehicle seat belts or a soft latch system.
[0004] To ensure that the child safety seat or seat base is properly installed in the vehicle, it is necessary for the installer to properly engage the vehicle seat belts or soft latch straps with the child safety seat or seat base and to ensure that any remaining slack is removed from the vehicle seat belts or soft latch straps so that, in the event of an accident, movement of the child safety seat or seat base relative to the vehicle is reduced.
[0005] In many cases, the end user of the child safety seat or seat base will not have the strength or dexterity to remove remaining slack from the vehicle seat belts or soft latch straps prior to use, resulting in a less than ideal installation of the child safety seat or seat base.
[0006] It is against this background that the present disclosure has been developed. Utility Model Content

[0028] Reference now Figure 1 , shows a child restraint 1 configured to be fixed to a vehicle seat, the child restraint 1 comprising: a restraint body 10, the restraint body 10 being configured to receive a belt in an untensioned state; and a tensioning mechanism 20, the tensioning mechanism 20 comprising a clamping member 30 pivotally attached relative to a portion of the restraint body 10, wherein the clamping member 30 is rotatable between a first position adjacent to the restraint body 10 and a second position displaced from the restraint body 10, wherein placing the clamping member 30 in the second position allows the restraint body 10 to receive the belt, and movement of the clamping member 30 from the second position to the first position presses a portion of the clamping member 30 against the belt, so that a portion of the belt is displaced by the clamping member 30 to fix the child restraint 1 to the vehicle seat in a tensioned configuration, wherein the tensioning mechanism 20 further comprises a locking member 40 pivotally attached relative to the clamping member 30, the locking member 40 being configured to engage with a portion of the restraint body 10 to lock the clamping member 30 in the first position.
[0029] In the illustrated embodiment, it can be seen that the child restraint 1 is in the form of a child seat, wherein the restraint body 10 is in the form of a seat body 10, including a seat portion 11 and a backrest portion 12. It will also be appreciated that the child restraint may also be in the form of a child seat and a seat base, wherein the restraint body 10 is in the form of a seat base configured to receive a child seat.
[0030] refer to Figure 2, it can be seen that the clamping member 30 includes a first end 31 and a second end 32, wherein the first end 31 of the clamping member 30 is configured to be pivotally attached relative to the seat body 10, and the second end 32 is configured to be pivotally attached relative to the locking member 40. The clamping member 30 also includes a first upper surface 33 and a second lower surface 34. It should be understood that when the clamping member 30 is in the first position, the upper surface 33 of the clamping member 30 forms a portion of a continuous seating surface for the occupant, and a portion of the lower surface 34 of the clamping member 30 is configured to abut a portion of the belt. It should be understood that in some cases, the belt 2 is in the form of a vehicle seat belt and may include a shoulder section and a leg section, and the movement of the clamping member 30 from the second position to the first position presses a portion of the clamping member 30 against either or both of the shoulder section or the leg section of the vehicle seat belt, so that a portion of either or both of the shoulder section or the leg section is displaced by the clamping member 30. It should also be understood that in some cases, the vehicle seat belt may include only a leg section, and the movement of the clamping member 30 from the second position to the first position presses a portion of the clamping member 30 against the leg section of the vehicle seat belt, so that a portion of the leg section is displaced by the clamping member 30. In other cases, the belt 2 is part of a soft latch system, wherein the belt 2 carries two anchor latches that are configured to connect to corresponding anchor points built into the vehicle structure. The soft latch system will typically have one or more adjustment mechanisms that allow the length of the belt between the two anchor latches to be adjusted, thereby allowing excess belt to be withdrawn. In one form, a portion of the belt for the soft latch system may be fixed relative to the child restraint by a tether arrangement and may be stowed in or on the child restraint when not in use and moved to an appropriate position relative to the tensioning mechanism when in use. In other forms, the soft latch system will be a separate component that is not fixed relative to the child restraint.
[0031] refer to Figure 8 , it can be seen how the clamping member 30 interacts with the seat body 10 and the strap 2 to increase the effective travel path of the strap 2 when the clamping member 30 is in its first position. It will be appreciated that the increase in the effective travel path of the strap 2 pulls more of the strap into the seat body 10, which will remove slack in the strap 2 and have the effect of pulling the child seat 1 against the vehicle seat.
[0032] It should be further understood that when the clamping member 30 is moved to the first position, the belt 2 is placed under tension and the belt 2 generates a reaction force that pushes the clamping member 30 back upward. It should be understood that once the clamping member 30 is in the first position, the locking member 40 is able to rotate toward the locked position in which the locking member 40 engages a portion of the seat body. It should also be understood that as the locking member rotates toward the locked position, an upward force will continue to act on the clamping member. Due to the fact that the locking member is rotatably connected relative to the clamping member, this upward force will also act on the locking member.
[0033] It can be seen that the locking member 40 includes a pair of protrusions 41 that are configured to engage with a pair of corresponding apertures 14 formed in the seat body 10. For the purposes of this description, the relationship between the corresponding protrusions 41 and the apertures 14 will now be described in the singular, however it should be understood that any number of protrusions and corresponding apertures may be provided.
[0034] refer to Figure 4 and Figure 5 When the clamping member 30 has been moved to its first position, the locking member 40 can then be rotated toward the locked position in which the projection 41 begins to move into its opening in the corresponding aperture 14. The aperture 14 has a first bearing surface 16 against which the outer surface 42 of the projection 41 is configured to abut when the locking member 40 enters the aperture opening and is rotated toward the locked position.
[0035] Reference Fig. 9 , it can be seen that the aperture 14 has a stop surface 17, and a first inclined surface 18 and a second inclined surface 19 separated by a transition region 21. It can also be seen that the protrusion 41 has a contact portion 43 and a stop surface 49. When the stop surface 49 on the protrusion 41 abuts against a corresponding stop surface 17 provided in the aperture 14, the locking member 40 will reach the locked position. The purpose of the first inclined surface 18 and the second inclined surface 19 and the contact portion 43 will be described in further detail below.
[0036] As the locking member 40 continues to rotate toward the locked position, the contact portion 43 provided on the protrusion 41 contacts and abuts against the first inclined surface 18 provided in the aperture 14. The first inclined surface 18 is configured to resist the rotation of the locking member 40 when the contact portion 43 of the protrusion 41 abuts against the locking member 40 to slide toward the locked position. Once the contact portion 43 has passed the transition region 21, the second inclined surface 19 is configured not to resist rotation (or to provide less resistance to rotation) when the protrusion 41 moves toward the locked position. It should be understood that once the contact portion 43 of the protrusion 41 passes the transition region 21, the reduced resistance and upward force from the belt 2 acting on the locking member 40 will cause the locking member 40 to continue to rotate to the locked position.
[0037] It will be appreciated that when the locking member 40 is rotated away from the locked position, the opposite occurs, wherein the second inclined surface 19 of the aperture 14 will resist rotation of the locking member 40 as the contact portion 43 of the projection slides against it, and then, once the contact portion 43 has passed the transition region 21, the first inclined surface 18 is not configured to resist rotation. It will again be appreciated that once the contact portion 43 of the projection 41 has passed the transition region 21, the reduced resistance and upward force from the belt 2 acting on the locking member 40 will cause the locking member 40 to continue to rotate away from the locked position. It can also be seen that the locking member 40 includes a first section 44 in the form of a rod that is configured to be actuated by a user when operating the tensioning mechanism 20. It can be seen that the first section 44 includes a first end 45 that is configured to be rotatably connected to the second end 32 of the clamping member 30, and a pair of projections 41 extend from the first end 45. The first section 44 also includes a second end 46 opposite the first end 45 and the projection 41, and a first upper surface 47 and a second lower surface 48. It should be understood that when in the locked position, the upper surface 47 of the locking member 40 forms a portion of a continuous seating surface for an occupant, and a portion of the lower surface 48 of the locking member 40 is configured to abut a portion of the backrest portion 12 of the seat body 10.
[0038] It can also be seen that the backrest portion 12 has a recessed portion 13 in which the locking member 40 is located when in its locked position, thereby ensuring that the seating surface is continuous when the occupant is seated. The recessed portion 13 is sized so that a user who wants to unlock the tensioning mechanism 20 can fit their finger behind a portion of the second end 46 of the first section 44 of the locking member 40 to pull the locking member 40 away from the recessed portion 13 and the backrest 12, thereby rotating it out of the locked position. It should be understood that the size and / or dimensions of the recessed portion 13 are not limited to the size and / or dimensions shown in the figures. In another form, the recessed portion can be larger than the user's finger, in another form, it can be smaller so that the user's finger cannot fit, and conversely, the locking member can have an alternative means of pulling the locking member 40 away, such as a hook or strap.
[0039] Although in the illustrated embodiment, the clamping member 30 is pivotally attached relative to the seat portion 11 of the seat body 10, and the locking member 40 is configured to abut a portion of the back portion 12 of the seat body 10, it should be understood that the position of the tensioning mechanism 20 can be changed and still fall within the intended scope of the present disclosure. For example, the clamping member 30 is pivotally attached relative to the back portion 12, and the locking member 40 can be configured to abut a portion of the seat portion 11.
[0040] Reference again Figure 6 and Figure 7 It should be understood that when the locking member 40 is in the locked position, the stop surface 49 and the contact portion 43 of each protrusion 41 abut against their respective stop surfaces 17 and the second inclined surface 18 formed in each aperture 14, and the lower surface 48 of the locking member 40 abuts against a portion of the backrest 12. It should be understood that the clamping member 30, the locking member 40 and the seat body 10 have formed an arrangement in which the clamping member 30 is fixed in place and cannot be moved from this position by external forces acting thereon.
[0041] It will be appreciated that once locked, any forces acting on the clamping member 30 (e.g., reaction forces from tension in the strap 2) will be transmitted through its first end 31 (which is pivotally connected relative to the seat body 10 and its second end 32) and then transferred into the first end 45 of the locking member 40, wherein the first end 45 of the locking member is prevented from being lifted off by the stop surface 49 and contact portion 43 of each protrusion 41 against their respective stop surface 17 and the second inclined surface 18 formed in each aperture 14 and the lower surface 48 against the backrest 12. It will be appreciated that the clamping member 30 can only be rotated out of the first position when the locking member 40 is rotated out of the locked position.
[0042] It should also be understood that this arrangement allows one-handed operation of the tensioning mechanism 20 without the need to actuate any additional locking elements. In addition, once the locking member 40 is in the locked position, it is clear that the clamping member 30 has been locked in place by virtue of the locking member 40 resting in the corresponding recessed portion 13 of the seat body 10.
[0043] It will be further appreciated that both the clamping member 30 and the locking member 40 provide upper surfaces 33, 45 that match the corresponding contour of the remainder of the continuous seating surface for the occupant, and that the lower surfaces 34, 46 have a plurality of rib elements and hollow portions to increase the stiffness of the respective members while saving weight.
[0044] It can be seen that the tensioning mechanism 20 is pivotally attached relative to the seat body 10 via a hinge member 50 , wherein the hinge member 50 is configured to be rigidly fixed to the seat body 10 , and the clamping member 30 is configured to be pivotally attached to the hinge member 50 via a hinge pin 51 .
[0045] The operation of the child seat 1 and the tensioning mechanism 20 will now be described with reference to the accompanying drawings:
[0046] To secure the child seat 1 to the vehicle seat using the vehicle seat belt: position the child seat 1 on the vehicle seat; unlock the locking member 40 and move the clamping member 30 to the second position (eg Figure 2 1 ); pass the seat belt buckle carrying the shoulder and lap portion of the vehicle seat belt 2 through the openings 4 formed in the two side wings 3 of the child seat 1, so that the vehicle seat belt 2 covers the seat body 10; fasten the vehicle seat belt 2 and pull out the excess belt; move the clamping member 30 to the first position, pushing against the vehicle seat belt 2; once in the first position (as shown in FIG. Figure 5 As shown), the locking member 40 is rotated toward the locking position, in which the protrusion 41 of the locking member 40 abuts against a stop surface (such as a stop surface) provided in a corresponding recess 13 formed in the seat body 10. Figure 7 shown).
[0047] To secure the child seat 1 to the vehicle seat using the soft latch system: position the seat 1 on the vehicle seat; unlock the locking member 40 and move the clamping member 30 to the second position (eg Figure 2 ); pass the anchor latch through the corresponding holes 4 formed in the two side wings 3 of the child seat so that the soft latch belt 2 covers the seat body 10; connect the anchor latch to the corresponding anchor point and pull out the excess belt; move the clamping member 30 to the first position, pushing against the soft latch belt 2; once in the first position (as shown in FIG. Figure 5As shown), the locking member 40 is rotated toward the locking position, in which the protrusion 41 of the locking member 40 abuts against a stop surface (such as a stop surface) provided in a corresponding recess 13 formed in the seat body 10. Figure 7 shown).
[0048] It should be appreciated that when the locking member 40 is rotated to the locked position and the contact portion 43 passes through the transition region 21, the locking member 40 can be rotated with sufficient force so that an audible "click" will be heard when the locking member 40 reaches the locked position and contacts are made between the two stop surfaces 49, 17 on the protrusion 41 and the aperture 14, and between the lower surface 48 of the locking member 40 and a portion of the backrest 12. Although such a "click" sound is not necessarily required, it should be appreciated that it is advantageous for the user to be assured that the locking member 40 has been moved to the locked position.
[0049] To remove the child seat 1 from the vehicle seat using the vehicle seat belt: rotate the locking member 40 away from the locking position until the vehicle seat belt pushes the clamping member 30 upwards; move the clamping member 30 towards the second position (eg Figure 2 ); unfasten the buckle of the vehicle seat belt 2 and pass the buckle carrying the shoulder and buckle part of the vehicle seat belt 2 rearwardly through the aperture 4 formed in the two side wings 3 of the child seat 1; return the clamping member 30 to the first position and rotate the locking member 40 to the locking position; remove the child seat 1 from the vehicle 20 seat.
[0050] To remove the child seat 1 from the vehicle seat using the soft latch system: rotate the locking member 40 away from the locked position until the soft latch belt pushes the clamping member 30 upward; move the clamping member 30 toward the second position (eg, Figure 2 release the anchor latch and return it through the aperture 4 formed in the two side wings 3 of the child seat 1; return the clamping member 30 to the first position and rotate the locking member 40 to the locked position; remove the child seat 1 from the vehicle seat.
[0051] In this embodiment, the tensioning mechanism 20 is pivotally attached relative to the seat portion (11) of the seat body (10) and is used when the child seat 1 is in the rearward-facing mode. However, it will be appreciated that in alternative arrangements the tensioning mechanism may be pivotally attached relative to the backrest portion (12). The tensioning mechanism may also be used in the child seat when in the forward-facing mode. In yet another embodiment, the child seat may be provided with more than one tensioning mechanism.
[0052] It will be appreciated that when considering the operation of the tensioning mechanism of an alternative child restraint, such as a base for a child seat or a child seat of alternative design, there may be some differences between the operations described above. For example, the above description contemplates the belt 2 or anchor latch passing through the aperture 4 formed in the side wing 3 of the child seat 1, however it will be appreciated that an alternative child restraint may not have an aperture through which the belt or anchor latch passes, and this step would not be required.
[0053] Throughout the specification and the claims that follow, unless the context requires otherwise, the words "comprise" and "include" and variations such as "comprising" and "including", will be understood to imply the inclusion of a stated integer or groups of integers but not the exclusion of any other integer or groups of integers.
[0054] The reference to any prior art in this specification is not, and should not be taken as, an admission of any kind that such prior art forms part of the common general knowledge.
