In addition, the child restraint harness 100 can include a chest clip device 130 operable to properly position the two shoulder straps 114A and 114B.
[0012] In conjunction with Figure 1, Figure 2 is a partially enlarged view illustrating the chest clip device 130, Figure 3 is a schematic view illustrating the chest clip device 130 in a detached state, and Figure 4 is a cross-sectional view of the chest clip device 130. The chest clip device 130 can include a first chest clip connector 132 held with a first shoulder strap (e.g., the shoulder strap 114A), and a second chest clip connector 134 held with a second shoulder strap (e.g., the shoulder strap 114B). It would be appreciated that the arrangement of the connectors 132 and 134 can be mutually interchanged on the shoulder straps 114A and 114B. The chest clip connectors 132 and 134 can engage and lock with each other at different positions so as to set a desirable width of the chest clip device 130 (i.e., a transversal distance between a first point on the chest clip connector 132 and an opposite point on the chest clip connector 134). The multiple positions for attaching the chest clip connectors 132 and 134 can allow to set different distances between the shoulder straps 114A and 114B. Each of the chest clip connectors 132 and 134 can be provided with slots 136A and 136B through which the associated shoulder straps 114A and 114B can be routed vertically and held with the connectors.
[0013] Referring to Figures 3 and 4, the chest clip connector 132 can include a tab portion 140 having a recessed portion that forms a tongue 146. A proximal end of the lo recessed portion (i.e., closer to the slots 136 where the shoulder straps 114A are routed) can be defined by a sidewall 144. The tongue 146 can include a resilient engaging part 148 that is connected with the tongue 146 near a distal end 146A of the tongue 146 (i.e., distal from the shoulder straps 114A). The engaging part 148 can have a free end 148A
located at a middle region of the tongue 146 between the sidewall 144 and the distal end 146A of the tongue 146. The free end 148A of the engaging part 148 can be provided with a protruding knob 149. The knob 149 can exemplary have a circular shape, but any shapes may be applicable. The chest clip connector 132 comprised of the tab portion 140, the tongue 146, the engaging part 148 and the knob 149 can be formed integrally in a single body by plastics molding. The slots 136A can be formed at two sides of the tab portion 140 through which the shoulder strap 114A can be routed to wrap around the tab portion 140. Accordingly, the chest clip connector 132 can be movably adjusted along the shoulder strap 114A.
located at a middle region of the tongue 146 between the sidewall 144 and the distal end 146A of the tongue 146. The free end 148A of the engaging part 148 can be provided with a protruding knob 149. The knob 149 can exemplary have a circular shape, but any shapes may be applicable. The chest clip connector 132 comprised of the tab portion 140, the tongue 146, the engaging part 148 and the knob 149 can be formed integrally in a single body by plastics molding. The slots 136A can be formed at two sides of the tab portion 140 through which the shoulder strap 114A can be routed to wrap around the tab portion 140. Accordingly, the chest clip connector 132 can be movably adjusted along the shoulder strap 114A.
[0014] The chest clip connector 134 can include a hollow interior forming an insert slot 150 in which the tongue 146 of the chest clip connector 132 can insert along a displacement axis X. The chest clip connector 134 can be formed with a catch structure 152 with which the engaging part 148 can engage and lock at different positions. The catch structure 152 can extend as a sidewall of the insert slot 150, and include two openings 156 and 158 distributed along the axis X and communicating with the insert slot 150. The shape of the openings 156 and 158 can be configured to complementary mate with that of the knob 149, such as a circular shape as shown. However, any other shapes may be suitable. The openings 156 and 158 are shown sideways connected with each other along the axis X, ridges 160 being interposed between the openings 156 and 158. In alternate embodiments, the openings 156 and 158 may also be entirely disconnected from each other.
The chest clip connector 134 comprised of the catch structure 152 can be formed integrally in a single body by plastics molding.
The chest clip connector 134 comprised of the catch structure 152 can be formed integrally in a single body by plastics molding.
[0015] Exemplary operation of the chest clip device 130 is described hereafter with reference to Figures 1-5. After the child is attached with the child restraint harness 100, the chest clip connectors 132 and 134 can be vertically adjusted to a suitable height approximately corresponding to the level of the child's armpits. The tongue 146 of the chest clip connector 132 then can be inserted along the axis X into the insert slot 150 of the chest clip connector 134 until the knob 149 engages and locks with any of the openings 156 and 158 by elastic deflection of the engaging part 148 in a direction substantially perpendicular to the axis X.
[0016] For example, should the child have a smaller body, the tongue 146 can be inserted into the insert slot 150 until the knob 149 engages and locks with the opening 156 of the catch structure 152 and the catch structure 152 abuts against or is positioned substantially adjacent to the sidewall 144. As shown in Figures 1 and 2, the locking engagement of the chest clip connector 132 at this first position of the chest clip connector 134 can allow the chest clip device 130 to hold the two shoulder straps 114A
and 114B
apart from each other at a narrower first distance Dl. In the embodiment where the openings 156 and 158 are sideways connected with each other, the ridges 160 can retain the knob 149 engaged with the opening 156 and prevent it from moving into the opening 158.
and 114B
apart from each other at a narrower first distance Dl. In the embodiment where the openings 156 and 158 are sideways connected with each other, the ridges 160 can retain the knob 149 engaged with the opening 156 and prevent it from moving into the opening 158.
[0017] Should the child have a larger body, the knob 149 can engage and lock with the opening 158 of the catch structure 152 such that the catch structure 152 is positioned farther away from the sidewall 144. As shown in Figure 5, the locking engagement of the chest clip connector 132 at this second position of the chest clip connector 134 can allow the chest clip device 130 to hold the two shoulder straps 114A and 114B apart from each other at a distance D2 greater than the distance Dl.
[0018] Referring to Figure 4, an end of the insert slot 150 may form a narrow passage 162 that has at least a dimension (e.g., height) smaller than the insert slot 150.
The length of the tongue 146 may be such that the distal end 146A of the tongue 146 can remain engaged in the passage 162 regardless of whether the knob 149 is locked with any of the openings 156 and 158. Since the connector 132 can engage with the connector 134 through at least two spaced-apart locations, i.e., engagement of the distal end 146A with the passage 162 and engagement of the knob 149 with the catch structure 152, secure attachment of the chest clip device 130 can be provided.
The length of the tongue 146 may be such that the distal end 146A of the tongue 146 can remain engaged in the passage 162 regardless of whether the knob 149 is locked with any of the openings 156 and 158. Since the connector 132 can engage with the connector 134 through at least two spaced-apart locations, i.e., engagement of the distal end 146A with the passage 162 and engagement of the knob 149 with the catch structure 152, secure attachment of the chest clip device 130 can be provided.
[0019] To unlock the chest clip device 130, the knob 149 exposed through the opening 156 or 158 can be depressed so as to disengage from the opening 156 or 158.
Being unlocked, the chest clip connector 132 then can be removed from the chest clip connector 134, or adjusted to set a desirable distance between the shoulder straps 114A and 114B.
Being unlocked, the chest clip connector 132 then can be removed from the chest clip connector 134, or adjusted to set a desirable distance between the shoulder straps 114A and 114B.
[0020] It is appreciated that modifications of the principles of design described herein may be possible. For example, in the illustrated embodiment, the engaging part 148 is exemplary shown as deflecting back and forth to engage and disengage the catch structure 152. In alternate embodiments, the engaging part and the catch structure may be disposed such that the engaging part can deflect vertically up and down to engage and disengage the catch structure. This may be achieved by changing the engaging part and the catch structure to an up/down relationship, which may be arranged at an upper and/or lower location of the connectors 132 and 134.
[0021] At least one advantage of the child restraint harness described herein is the ability to provide a chest clip device 130 that can be able to hold the shoulder straps 114A
and 114B apart from each other at different distances according to the size of the child.
and 114B apart from each other at different distances according to the size of the child.
