Description

Vehicle safety seat that can be used interchangeably with two and three points {Car Seat}

The present invention relates to a car seat. Specifically, the present invention relates to a safety seat mounted on a vehicle seat to support an infant for the safety of infants during vehicle operation, and secures safety based on a head portion provided with wings, and the seat belt is a two-point type and/or It is fixed in a three-point type for high compatibility, and it is easy to store by applying a structure that can fold the head and seating parts through hinge rotation, and at least one of a fixing device, an adjustment lever, a set clip, a rotation fixing device and a hanging fixing device. Regardless of the type of belt (NLR, ALR, ELR, etc.) by using some, it relates to a car seat that is secured by securing the belt in a state where there is no shaking.

In general, when boarding various vehicles including a passenger car, the vehicle is operated while wearing a seat belt for the safety of the occupants.

However, as seat belts provided in various vehicles including passenger cars are installed based on adults, infants and children who are relatively small in size compared to adults cannot wear seat belts. For the safety of infants, a separate infant safety seat is installed on the vehicle's seat and used.

In addition, as the demand for private cars increases rapidly, the demand for safety seats for infants is also increasing rapidly.

In the form of this safety seat for infants, spores of cushioning material are surrounded by the front and both sides on the body of the seat-type without legs made of synthetic resin, and a pair of fastening belts connecting the upper front of the backrest to the floor surface are mounted. As a structure, the infant seated in such a car seat is to protect the safety of the infant against the impact of the vehicle by inhibiting the movement of the body by a fastening belt that is fastened between the crotch through both shoulders.

However, the conventional safety seat for a vehicle as described above has a disadvantage in that it is very cumbersome to attach or detach it to a seat using a seat belt of a vehicle because of its large size and heavy weight.

In addition, there is a problem in that there is no structure that can be applied by mixing a two-point type and a three-point type for fixing the vehicle safety seat, and it is difficult to store the car seat when the car seat is separated due to its large volume and weight.

In addition, the fixed state between the vehicle and the safety seat is incomplete according to the driving state of the vehicle such as cornering and sudden stop, so that the infant is separated from the safety seat, and there is a big problem in the safety of the infant.

In particular, there is a problem in that the safety of infants is hardly guaranteed by the car seat because the car seat is not tightly fixed depending on the type of belt (NLR, ALR, ELR, etc.).

Therefore, there is a growing need for a structure that can solve these problems.

Belt fixing structure-5th embodiment

13 shows a structure for fixing the belt in a state where there is no shaking regardless of the type of the belt by using the hanging fixing device proposed by the present invention.

13(a) and (b), the hanging fixing part 80 according to the present invention is provided on at least a part of the seating body part 30, and a three-point passage part of the trunk wing part 40 ( 41) or may include a hook portion 81 for hanging the belt passing through the two-point passage portion 42.

In addition, the hanging fixing part 80 further includes a rotating part 82 for additionally winding the belt hung on the hanging part 81 through a rotating operation.

In this case, in proportion to the rotation of the rotating part 82, a fixed degree between the vehicle safety seat 1 and the vehicle may be strengthened.

That is, in proportion to the rotation of the rotating part 82, the belt is pulled and fixed in tension, so that the vehicle safety seat 1 and the vehicle can be fixed in place.

Effects according to the invention

The present invention relates to a safety seat mounted on a vehicle seat to support the infant for the safety of infants during vehicle operation, and it is possible to secure safety based on a head portion having wings.

In addition, in the present invention, high compatibility can be ensured by fixing the seat belt in a two-point type and/or a three-point type.

In addition, in the present invention, high storage properties can be secured by applying a structure in which the head portion and the seating body portion can be folded through a hinge rotation.

In addition, the present invention uses at least some of a fixing device, an adjustment lever, a set clip, a rotation fixing device, and a hanging fixing device to fix the belt in a state without shaking, regardless of the type of the belt (NLR, ALR, ELR, etc.). By doing so, it is possible to provide a car seat with guaranteed safety.
