Description

Car Seat {Carseat}

The present invention relates to a car seat, and more particularly, to a car seat.

Generally, when a vehicle such as a passenger car is carried, the safety belt is operated for the safety of the passenger. However, most of the safety belts and most of the safety devices attached to the vehicle are installed on the basis of adults. In case of infants or children who are accompanied by the driver, There was a problem.

This means that infants and children, who are relatively small in size compared to adults, are not likely to wear safety belts and thus are exposed to great risk. If infants or children wear the seat belt directly, Because it is not designed to cause injury to the abdomen and neck (where the belt passes).

In order to solve this problem, a separate protective sheet for infants, a so-called baby car seat is mounted on a seat of a vehicle, and the vehicle is operated while the infant is seated in the car seat.

Various methods for fixing the child car seat to the backrest of the vehicle seat have been developed variously, and a structure for stably fixing the child to the car seat has also been developed variously.

A commonly used method of fixing a child car seat to the back of a vehicle seat is to pass the seat belt used by a vehicle occupant through a fastening space formed on one side of the child car seat to fasten the seat belt buckle to each other, To the back of the seat.

This method is disadvantageous in that a shock applied to an infant is large because the infant car seat is instantly lifted up from the back of the vehicle seat due to an accident impact without the infant car seat sticking to the back of the vehicle seat at the time of an accident.

In order to solve such a problem, recently, a method has been recently developed in which a separate engaging member is provided at the lower rear side of the seat portion of the child car seat made up of the seat portion and the backrest portion and the engaging member is fastened to a frame provided inside the vehicle seat .

Conventionally, there has been a problem in that when the joining member is used, the vehicle can not be unified by using a method for each vehicle, resulting in an increase in the erroneous mounting rate of the car seat. The International Organization for Standardization (ISO) has defined the method (ISO 13216) to secure the car seat safely in the vehicle by unifying the methods of each car in order to secure the car seat securely. The fixed standardization method is called ISOFIX.

Isopix has dramatically reduced the erroneous installation rate of the existing seat of the child car seat, but it is still insufficient for the perfect installation.

Therefore, in order to secure the safety of the infant and to preserve the life of the infant, many researches and developments have been made recently to prevent the infant car seat from being installed in the seat of the vehicle.

The booster body 200 is formed in a cushion shape between the car seat body 100 and the vehicle seat so that the upper side is coupled to the car seat body 100 and the lower side is in contact with the vehicle seat, To be indirectly connected to the seat.

The booster body 200 can not be positioned at a height suitable for binding the car seat body 100 with a vehicle belt manufactured on the basis of an adult by simply sitting on the car seat body 100, (1) to the vehicle seat is weakened or the infant is injured.

Hereinafter, the booster body 200 will be described in detail with reference to FIGS. 1 and 2. FIG.

The booster body 200 may be connected such that the upper side thereof is rotatable with respect to the carousel body 100. This is the same as described for the car body 100.

The booster body 200 can be detachably coupled to the booster coupling device 300 at the lower side and the booster coupling device coupling spaces 210 and 220 at least at the lower side to house the booster coupling device 300 . At this time, the booster coupling device coupling spaces 210 and 220 may be formed by the size of the booster coupling device 300, and may be divided into the front booster coupling space 210 and the rear booster coupling device coupling space 22 .

The booster body 200 includes a sliding hole H1 and a fastening member C3 and C4 which are formed by extending a long hole so that the sliding members C1 and C2 can slide on the lower side, The first through third holes H2 through H4 may be formed in which the holes are formed so that the first through third holes H1 through H4 can be inserted or removed.

The booster coupling device 300 can be detached or coupled from the booster body 200 through the sliding hole H1 and the coupling holes 1 to 3 through H2 or H4, So as to be relatively slidable with respect to the booster body (200).

Implementation of the above-described detachment coupling structure or sliding structure will be described in detail in a booster coupling device 300 to be described later.

The booster coupling device 300 is detachably coupled to the booster body 200 and coupled to allow relative movement to the booster body 200 and connects the vehicle seat to the booster body 200. This will be described in detail below with reference to FIG. 3 and FIG.

Specifically, the booster coupling device 300 includes a body 310 coupled to the booster body 200, a coupling 320 coupled to one side of the body 310, a coupling 320 coupled to the other side of the body 320, And an operating portion 330 for operating the booster coupling device 300.

The body 310 includes a base member 311 on which the booster body 200 is separated or slidably moved and a head member 312 connected to one end of the base member 311 and to which the coupling portion 320 is mounted. And may be detachably coupled to the booster body 200 by the base member 311 or may be coupled to enable relative movement with respect to the booster body 200. [

The body portion 310 may be detachably coupled to the booster body 200 to allow the infant to be mounted on the vehicle seat in a forward or rearward view.

For example, the body 310 separated from the booster body 200 may be coupled to the booster body 200 in a state where the coupling portion 320 described later is located in the rear booster coupling space 220, And the coupling portion 320 is coupled to the booster body 200 while the coupling portion 320 is positioned in the front booster coupling space 210, the infant can be rearwardly mounted on the vehicle seat have. Such a detachment coupling mechanism will be described in detail in the operation section 320 described below.

Conventionally, a device for coupling to a vehicle seat is integrally coupled to the lower side of the booster body 200, so that it can not be changed if the front or rear view of the infant is determined. For the safety of infants, ordinary car seats are regulated so that 9 ~ 10kg of infant weighs 9 ~ 10kg (about 10 months of age), infants less than 9 ~ 10kg and infants more than 9 ~ 10kg.

Therefore, when the child weighs 9 ~ 10kg and the first car seat is purchased, the weight of the infant is more than 9 ~ 10kg. In order to do the front view, it is necessary to repurchase and the previous car seat must be discarded.

Accordingly, in the embodiment of the present invention, since the body 310 is detachably coupled to the booster body 200, it is possible to perform either the front view or the back view at any desired time, There is an advantage that the rear view is possible.

In other words, the car seat according to the present invention is an all-in-one product that can be used continuously without the need to purchase the car seat 1 according to the growth of the infant, thereby improving the financial satisfaction to consumers, There is a big effect and it has a great marketability.

In addition, the body portion 310 may be configured to allow relative movement with respect to the booster body 200, thereby forming a separation distance between the vehicle seat and the booster body 200. This will be described with reference to FIGS. 5 to 6. FIG.

For example, when the body portion 310 is slid and fixed to the booster body 200 in the direction of approaching the vehicle seat (forward direction), the distance between the booster body 200 and the vehicle seat becomes constant When the body portion 310 slides and moves relative to the booster body 200 in the direction away from the vehicle seat (rearward direction) and then fixed, the booster body 200 and the vehicle The distance between the seats can be connected to the vehicle seat in a state in which the distance between them is narrowed at a constant interval. The sliding mechanism described above may be configured such that when the body 310 and the booster body 200 are coupled with each other in a state where the coupling part 320 is positioned in the rear booster coupling space 220, As an example.

Conventionally, devices for coupling the car seat to the vehicle seat are disposed on the lower side of the booster body 200, respectively, to adjust the separation distance independently of each other. At this time, the left and right coupling devices were coupled to the vehicle seat independently of each other, and the right coupling device frequently failed to be coupled to the vehicle seat. In other words, a lot of car seats are mounted on the seat of the vehicle, which often causes a serious threat to the safety of the infant.

Therefore, in the embodiment of the present invention, the coupling portion 320 does not adjust the separation distance between the vehicle seat and the booster body 200, but rather, through the sliding movement of the body portion 310 relative to the booster body 200, The distance between the booster body 200 and the booster body 200 can be adjusted so that the rate at which the car seat 1 is erroneously mounted on the vehicle seat is remarkably reduced.

The coupling portion 320 may be coupled to one side of the body portion 310 and connected to the vehicle seat.

Specifically, the engaging portion 320 includes a first engaging member 321 which is connected to a 'C' shaped protrusion (not shown) provided at one side of the frame of the vehicle seat and disposed on the left side, A second coupling member 322 connected to the right-hand side of the " C " -shaped projection provided on the other side, and a first coupling member 321 and a second coupling member 322 integrally connected to each other, The connecting member 323 may be formed.

The first engaging member 321 and the second engaging member 322 may be formed in a complementary shape of 'c' so that one end thereof is coupled to each of the 'c' shaped protrusions of the vehicle seat, Member 323 as shown in Fig.

The first engaging member 321 and the second engaging member 322 are connected to the respective 'C' shaped protrusions of the vehicle seat so that the car seat 1 is firmly fixed to the vehicle seat. Here, the 'C' shaped protrusions and the first and second engagement members 321 and 322 provided on the frame of the vehicle seat may have an ISOFIX type connection structure which is an international standard.

The connection member 323 is rotatably coupled to the head member 312 formed at one side of the body 310 and has one end coupled to the first engagement member 321 and the other end coupled to the second engagement member 322, As shown in FIG.

When the car seat 1 is detached from the vehicle seat and then transported, the connecting member 323 rotates the first and second engaging members 321 and 322 in the direction of the car seat 1 so as not to protrude outside the booster body 200 can do.

The actuating portion 330 may be configured to cause the body portion 310 to be detached or engaged from the booster body 200 or to allow relative movement of the body portion 310 with respect to the booster body 200 .

The actuating portion 330 may include a first operating mode for performing the relative movement to the booster body 200 to determine the separation distance between the booster body 200 and the vehicle seat, And a second mode of operation for performing an operation of disengaging or engaging from the booster body 200 to determine the desired operating mode.

The detailed configuration of the operation unit 330 will be described in detail to explain the first and second operation modes.

The operation unit 330 includes a pull member 331 for instructing to perform the first or second operation mode, a connection belt 332 for transmitting the external force of the pull member 331 to the base member 333, A base member 333 which is located inside the base member 333 and performs the first or second operation mode by an instruction of the pull member 331, a spring S and a base member 333 which generate a restoring force on the base member 333, And a stopper member 335 for stopping the sliding of the base member 333.

The pull member 331 instructs the base member 333 to perform the first operation mode or the second operation mode so that the external force of the protector is transmitted to the base member 333 through the connection belt 332. [

The connection belt 332 connects the pull member 331 and the base member 333 and transmits the external force of the pull member 331 to the base member 333 and can be realized as a belt material.

The base member 333 is located inside the body portion 310 and is connected to the handle member 331 through the connection belt 332. The base member 333 is connected to the body portion 310 by the external force of the handle member 331, And can perform the first operation mode or the second operation mode by sliding.

The base member 333 is engaged so that the first and second sliding members C1 and C2 and the first and second fastening members C3 and C4 are slidable.

Specifically, the base member 333 includes first and second sliding member movement lines L1 and L2 and first and second fastening members C1 and C2 in which the first and second sliding members C1 and C2 slide and contact and move, The first and second fastening member movement lines L3 and L4 that slide and contact the first and second fastening members C3 and C4 may be formed.

The first and second sliding members C1 and C2 are fixed to the first fixing holes HCl formed on the outer surface of the body portion 310 so that the first and second sliding member movements of the base member 333 Off contact that is inserted into or released from the sliding hole H1 formed in the sliding hole H1 formed in the booster body 200 by sliding contact with the lines L1 and L2.

The first and second fastening members C3 and C4 are fixed to the second fixing hole HC2 formed on the outer surface of the body portion 310 and the first and second fastening member movements of the base member 333 Off contact to be inserted or released into the coupling first to third holes H2 to H4 formed in the booster body 200 by sliding contact with the lines L3 and L4.

The first and second sliding member moving lines L1 and L2 are provided on a line that slidably contacts the first and second sliding members C1 and C2 with the sliding hole H1 (The line from the second point P2 to the first point P1), which is inserted or released in the sliding hole H1.

Here, the line that makes sliding contact with the sliding hole H1 is formed on the base member 333 with a hole extending in a direction parallel to the line including the relative movement directions A and B of the booster coupling device 300, The line to be inserted or released in the sliding hole H1 may be formed so that the hole extends obliquely in the direction toward the inside of the base member 333 from one side of the line slidingly contacting the sliding hole H1.

The first and second fastening member movement lines L3 and L4 are connected to the first and second fastening members C3 and C4 via the on- (The line from the sixth point P6 to the fourth point P4). Here, the line to be inserted or released in the first to third holes H2 to H4 may be formed to extend obliquely in the direction of the inside of the base member 333.

The spring latch 334 is hooked on one surface of the base member 333 and is connected to the spring S mounted on the body 310 so that the movement of the base member 333 can be controlled have.

The spring latch 334 transmits an external force supplied by the pull member 331 to the spring S to the spring S to generate a restoring force of the spring S and the external force by the pull member 331 is released The restoring force is transmitted to the base member 333 so that the base member 333 can be returned.

The stopper member 335 controls the movement of the operation unit 330 to the first operation mode and the second operation mode and controls the movement of the base member 333 in the direction A And can be coupled in the vicinity of the connection belt 332 forming portion.

Specifically, when the stopper member 335 is positioned at the operating position, the first operating mode of the operating portion 330 is driven, and when the operating portion 330 is in the released position, the first operating mode and the second operating mode of the operating portion 330 All of which can be controlled to be driven.

Here, the stopper member 335 can be converted to the release position when the basic position is the operating position and applies an external force in one direction. For example, when an external force is applied to the left side, the release position, and when the external force is released, the operation position may be the basic position.

When the stopper member 335 is located at the operating position, the operating portion 330 is implemented only in the first operating mode.

When the operating portion 330 pulls the pull member 331 in the direction A to change the connection distance between the booster body 200 and the vehicle seat, the base member 333 translates in the A direction. At this time, the stopper member 335 is in the operating position, and the base member 333 abuts against the stopper member 335 at an arbitrary point, so that the movement is prevented.

This allows the first and second sliding members C1 and C2 of the base member 333 to move from the third point P3 to the second point P2 of the first and second sliding member moving lines L1 and L2 And the first and second fastening members C3 and C4 are movable only from the sixth point P6 to the fifth point P5 of the first and second fastening member movement lines L3 and L4 .

When the stopper member 335 is placed in the unlocked position, the operating portion 330 can implement both the first operating mode and the second operating mode.

The operation member 330 pulls the knob member 331 in the direction A as far as possible to separate the booster coupling device 300 and the booster body 200 so that the base member 333 translates in the A direction. At this time, since the stopper member 335 is in the release position and does not come into contact with the stopper member 335 at any position with respect to the base member 333, the base member 333 does not move, And becomes movable.

This causes the first and second sliding members C1 and C2 of the base member 333 to move from the third point P3 of the first and second sliding member moving lines L1 and L2 to the first point P1 And the first and second fastening members C3 and C4 are movable from the sixth point P6 to the fourth point P4 of the first and second fastening member movement lines L3 and L4 .

However, in this case, the first operating mode can also be implemented.

In this case, since the stopper member 335 is not in the operating position but in the releasing position, the base member 333 can be translationally moved in the A direction or the B direction, and the degree of pulling the pull member 331 in the A direction The magnitude of the pulling external force) makes it possible to select the first operation mode or the second operation mode.

That is, if the pulling member 331 is pulled only to an arbitrary point in the direction A, the base member 333 is translated only in a direction A to an arbitrary point without stopping the stopper member 335. In this case, The first and second sliding members C1 and C2 of the first and second sliding members 331 and 333 are controlled to be movable only from the third point P3 to the second point P2 of the first and second sliding member moving lines L1 and L2 The first and second fastening members C3 and C4 are controlled to be movable only from the sixth point P6 to the fifth point P5 of the first and second fastening member movement lines L3 and L4.

In the embodiment of the present invention, only the first operation mode can be performed through the stopper member 335, and suddenly the booster coupling device 300 can be operated while changing the connection distance between the booster body 200 and the vehicle seat. The booster body 200 can be prevented from being accidentally separated from the booster body 200 so that malfunctions of the operation modes can be prevented and accurate and correct use of each operation mode can be achieved.

Further, since the first operation mode and the second operation mode can be easily and easily performed through the stopper member 335 at one-touch, there is an advantage that the operation modes can be smoothly used.

Hereinafter, a mechanism for performing the first and second operation modes through the above-described structure will be described.

First, the first to third points P1 to P3 on the first and second sliding member moving lines L1 and L2, which will be described later, And the fourth to sixth points P4 to P6 on the movement lines L3 and L4, respectively.
