Description

Height-adjustable child restraint device Technical Field The present invention relates to a height adjustable child restraint for use in a forward facing position. Background Child restraint devices (also known as car seats) are used to protect children during motor vehicle travel and are important to ensure safe and comfortable seating of children both on short trips and long trips. For this reason, work is continuously being performed to ensure that children and parents feel safe while riding on a bus. There are different types of child restraint devices on the market for children of different ages and heights. Infant carrier is used for infants from birth to about 12 months old. Infant carrier facilitates ingress and egress to the vehicle and allows the child to remain in the seat without having to be held up. When the child is slightly longer, a rearward facing car seat is the safest option. Rearward-facing car seats are typically mounted and fixed in vehicles and do not move frequently. There are many different versions of child height ranging from 105 cm to a maximum of 125 cm. Older children, preferably when their height has reached more than 125 cm, still use forward-facing car seats (also known as high-back booster seats or simply booster seats). As the name suggests, booster seats can raise a child to a height high enough for the lap and shoulder belts of the vehicle to safely restrain the child. This is desirable because vehicle safety systems, such as seat belts, are designed for individuals having heights of about 145 cm to 150 cm. Thus, booster seats may be considered as an adapter between a child and a vehicle safety system, and one primary purpose of a forward-facing child restraint is to ensure that the child's body is properly positioned relative to the vehicle seat belt. The installation and assembly of the child restraint may be performed by the harness of the vehicle or by using an ISOFIX connector (standard interface for child restraint). For this purpose, a child restraint with a height-adjustable seat section can be used. However, the height-adjustable seat section generally reduces the robustness of the child restraint and may cause the seat section to move away from the vehicle seat back in the event of an accident. This in turn may lead to safety hazards. For example, height adjustable seat sections based on scissor-fork technology have been found to present such problems. Disclosure of Invention It is an object of the present invention to overcome the above problems and to provide an improved height adjustable child restraint that enables children of different ages and heights to safely ride in a vehicle. According to a first aspect of the present invention, this and other objects are achieved by a height adjustable child restraint for use in a forward facing position, the child restraint comprising: A seat portion for holding a child and a base portion, wherein the base portion comprises An upper frame member for connection with a seat portion and a lower frame member to be placed on a vehicle seat, wherein at least one front beam connects a front portion of the upper frame member to a front portion of the lower frame member and at least one rear beam connects a rear portion of the upper frame member to a rear portion of the lower frame member such that a parallelogram is formed, and At least one guide plate connected to the lower frame member, and wherein at least one of the upper frame member and the back beam is movably connected to the guide plate for vertical movement of the upper frame member relative to the guide plate. The invention is based on the insight that by movably connecting the upper frame member and/or the rear beam to a vertically extending guide plate, the child seat can be raised or lowered while preventing the child seat from moving in a forward direction in case of an accident. In the event of an accident, the guide plate absorbs the forces acting on the seat section and brings it close to the backrest of the vehicle seat. Thus, the upper frame member is secured in a back position adjacent the vehicle seat, which is important for the seat belt to remain in the correct position on the child's body. Furthermore, the advantage of the parallelogram mechanism over the scissor mechanism is that the parallelogram mechanism is easier to lock, contains simpler parts and provides support/adaptation to the lower leg. The at least one guide plate may comprise a slide rail having an upper end position and a lower end position and extending substantially vertically, and wherein at least one of the upper frame member and the rear beam may comprise a protrusion adapted to slide along the slide rail. The slide rail may have a width, which is referred to herein as a first width. Thus, the protrusion may fit in the first width of the slide rail. The angle between the front beam and the lower frame member may be at least 5 degrees, preferably at least 10 degrees, when the pro
