The present invention relates to child safety seats.
A child safety seat is generally used in a vehicle to provide protection and reduce the impact of accidental collision on a child. For example, when a frontal collision occurs, the child safety seat can effectively prevent the child's body from abruptly moving forward which may result in harmful hitting impact. When a rearward collision occurs, a backrest portion and a headrest of the child safety seat can support the body and the head of the child, which can prevent abrupt rearward movement of the child's neck that would result in neck injuries. Child safety seats thus can reduce the risk of injuries and improve the safety of children in a vehicle.
However, when the vehicle is subjected to sideways collision, the conventional child safety seats can only rely on the sidewalls of the backrest portion and the sidewalls of the headrest to reduce the impact of the collision, which does not provide sufficient protection.
Therefore, there is a need for an improved child safety seat that can provide better cushioning against sideways collision.
The present application describes a child safety seat that can offer better protection and address at least the foregoing issue.
According to an aspect, a child safety seat includes a seat shell and a side protection part. The seat shell has a seat portion, a backrest portion and a sidewall, the sidewall protruding forward from the backrest portion and having a front edge. The side protection part is disposed adjacent to the sidewall at an inner side thereof and extends along the inner side of the sidewall from a location adjacent to the seat portion toward a top of the backrest portion, wherein the side protection part has a first and a second major surface opposite to each other, and an edge portion connected with the first and second major surface, the edge portion having a rib that protrudes from the second major surface and lies adjacent to the front edge of the sidewall of the seat shell.
According to another aspect, a child safety seat described herein includes a seat shell and a side protection part. The seat shell has a seat portion, a backrest portion and a sidewall, the sidewall protruding forward from the backrest portion. The side protection part is disposed adjacent to the sidewall at an inner side thereof and extends along the inner side of the sidewall from a location adjacent to the seat portion toward a top of the backrest portion, wherein the side protection part has one or more cushioning structure, and a first and a second major surface opposite to each other, the first major surface facing an inner space of the seat shell where is received a child and covering the one or more cushioning structure, and the second major surface facing the sidewall of the seat shell.
The two sidewalls 110 can protrude forward from the backrest portion 106, and can respectively extend along a left and a right side of the backrest portion 106. The two sidewalls 110 can sideways delimit an inner space of the seat shell 102 adapted to receive a child, and can provide sideways protection for the child's body. The backrest portion 106 can be assembled with an adjustable headrest 108 that is disposed between the two sidewalls 110. The headrest 108 can move along the backrest portion 106 between the two sidewalls 110 for adjustment in accordance with the height of a child placed in the seat shell 102.
According to an embodiment, the headrest 108 can have a central support portion 112, and two side support portions 114 respectively protruding forward at a left and a right side of the central support portion 112. The two side support portions 114 of the headrest 108 can provide sideways protection for the child's head.
The child safety seat 100 can further include two side protection parts 116 that are respectively disposed adjacent to the two sidewalls 110 at an inner side thereof. At each of the left and right side, the side protection part 116 can extend along the inner side of the corresponding sidewall 110 from a location adjacent to the seat portion 104 toward a top of the backrest portion 106, a portion of the side protection part 116 being located between the sidewall 110 and the side support portion 114 of the headrest 108. According to an example of construction, the side protection parts 116 can exemplarily include, without limitation, plastic materials.
In conjunction with
The side protection part 116 can have one or more cushioning structure that is configured to provide elastic resilience and is deformable to cushion the impact of sideways collisions. Referring to
The position of the cushioning structure 120 can generally correspond to the headrest 108, which can provide cushioning for the headrest 108 during sideways collision. More specifically, the side support portion 114 of the headrest 108 may substantially overlap with a surface area of the cushioning structure 120, and the side support portion 114 and the cushioning structure 120 can remain overlapping each other within a range of vertical adjustment of the headrest 108. According to an example of construction, the cushioning structure 120 can have a surface area that is at least equal to a surface area of the side support portion 114, preferably slightly greater than the surface area of the side support portion 114.
The cushioning structure 120 can include one or multiple sunken region. A sunken region refers to a recess that is formed on the major surface 116B so that the cushioning structure 120 is distinctly visible on the major surface 116B. In the example illustrated in
According to yet another embodiment, the cushioning structure 120 may be formed as a hollow portion of the side protection part 116 having one or more inner cavities between the two major surfaces 116A and 116B. In this case, the cushioning structure 120 may not be visible on any of the major surfaces 116A and 116B. In an example where the cushioning structure 120 is a hollow portion having a single inner cavity, the single inner cavity can have a surface area substantially overlapping with the side support portion 114 of the headrest 108. In another example where the cushioning structure 120 is a hollow portion having a plurality of inner cavities, the inner cavities can occupy an area inside the side protection part 116 that substantially overlaps with the side support portion 114 of the headrest 108.
The cushioning structure 122 can be located below the cushioning structure 120, i.e., corresponding to a portion of the backrest portion 106 below the headrest 108. The cushioning structure 122 can be formed as one or more sunken region (i.e., formed on the major surface 116B) or a hollow portion (i.e., having one or more inner cavity formed between the two major surfaces 116A and 116B). According to an example of construction, the cushioning structure 122 can include a plurality of elongate sunken regions parallel to one another, as shown in
According to an example of construction shown in
Advantages of the child safety seat described herein include the ability to provide effective cushioning against sideways collision. More specifically, the child safety seat includes side protection parts having cushioning structures that provide better elastic resilience and are adapted to at least partially dissipate the impact energy generated by sideways collisions. As a result, the child safety seat can offer better protection.
Realization of the child safety seat has been described in the context of particular embodiments. These embodiments are meant to be illustrative and not limiting. Many variations, modifications, additions, and improvements are possible. These and other variations, modifications, additions, and improvements may fall within the scope of the inventions as defined in the claims that follow.
