Description
Technical Field
The present invention relates to a fixing device of a safety seat (ISOFIX car seat), and more particularly, to a fixing device of a safety seat for fixing a safety seat to an interior of a vehicle, to which a child safety seat fixing system (ISOFIX) standard is applied.
Background
A safety seat (car seat) is a device that is attached to a car seat to prevent a safety accident when a child such as a newborn or an infant gets on the car, and is a device that safely protects the newborn or the infant when an emergency brake, an emergency departure, a collision, or the like occurs.
The conventional safety seat is used by being mounted and fixed to a car seat using a three-point angle Belt (Lap and KiagonalSeat Belt) for an adult of a vehicle or using only a two-point Belt. However, in many cases, the shape of each seat and the shape of the seat belt are different depending on the vehicle, and thus the fixing of the safety seat is unstable.
To solve such instability, a safety seat using an isofix (international standard and standardization) system has been developed, which is configured to include an anchor (anchor) on one side of an automobile seat and a latch (latch) coupled to the anchor on one side of the safety seat.
Such an ISOFIX system is a system in which a fixing device (plug pin) protruding from a safety seat is fastened to a fixing portion (anchor) on the inner side of a car seat to fix the fixing device. It is inconvenient because it is necessary to operate the safety seat in a narrow interior of the car, and there is a problem in visibility.
Further, since the ISOFIX type fixing devices (bolts) form a pair and each of the pair of fixing devices (bolts) needs to be protruded from the safety seat and fixed to an anchor of the car seat, the work load is large and troublesome. In particular, when the door of the vehicle is opened and the vehicle is operated at the outside, it is difficult to operate the fixing device (plug pin) relatively located at the inner side of the vehicle, and thus there is a problem that the operation efficiency is lowered.

The present specification relates to a fixing device for fixing a safety seat to a seat of an automobile, and more specifically, to a fixing device used when a child safety seat to which international standard organization fixing (isofix) is applied is fixed to an automobile.
First, a child safety seat (hereinafter, referred to as a "child safety seat") to which the fixing device of the present invention is applied will be described, in which a framework of the safety seat is constituted by a safety seat main body 12. The safety seat body 12 has an elastic bar 15 so as to support the back side. In this specification, although the structure of the entire safety seat is shown in the drawings, a detailed description of the seat portion 100 on which a child sits and the like will be omitted, and the portions related to the present invention will be mainly described. That is, the safety seat body 12 will be described mainly in the portions necessary for describing the present invention. For reference, as shown in fig. 1, the seat portion 100 may be disposed toward the elastic bar 15, or may be disposed reversely.
Fig. 1 shows the shape of the fixing device of the present invention before projection, and fig. 2 shows the shape of the fixing device projection. According to the present invention, a pair of the first and second fixing bodies 50 and 50' constituting the fixing means can be automatically protruded first by the operation of the driving lever 30, which will be discussed in detail hereinafter.
For reference, in the fixing device constituting the present invention, the fixing bodies 50, 50 'and the locking units 40, 40' form a pair, respectively. The pair of fixing bodies 50, 50 'and the locking units 40, 40' are symmetrically arranged by the same structure, and for convenience of description, the pair of fixing bodies 50, 50 'and the locking units 40, 40' are given different marks and names from each other. The pair of fixing bodies 50, 50 'are distinguished by a first fixing body 50 and a second fixing body 50', and the locking units 40, 40 'are distinguished by a first locking unit 40 and a second locking unit 40'. Further, the detailed structural elements are given the same reference numerals and names for explanation.
First, the safety seat main body 12 is explained. The safety seat main body 12 forms a lower skeleton of the safety seat, and a pair of housings 20 are formed inside thereof. The first and second fixing bodies 50 and 50' of the fixing device are inserted into the pair of housings 20 and moved, respectively. More precisely, a portion of the first and second fixing bodies 50 and 50' are linearly moved in a state of being inserted into the housing 20, respectively.
The housing 20 includes a main elastic member 52 therein, and the main elastic member 52 serves to provide elastic force to the first and second fixing bodies 50 and 50'. The main elastic member 52 has one end fixed to the inside of the case 20 and the other end connected to the first fixing body 50 and the second fixing body 50'. For reference, a state in which the housing 20 is removed and the main elastic member 52 is exposed is shown in fig. 4. In fig. 4, one end of the main elastic member 52 is separated as a free end, however, in actuality, the one end of the main elastic member 52 is fixed to the inside of the housing 20.
The fixture has a drive rod 30. The driving lever 30 is used to operate the fixing device, and if a user pulls the driving lever 30 to the outside of the safety seat body 12, the first locking unit 40 and the second locking unit 40 'constituting the fixing device are operated, thereby releasing the hooked state of the first fixing body 50 and the second fixing body 50'. The drive lever 30 is provided on the front surface of the safety seat main body 12. This is to improve the convenience of use for the user, and the user can easily operate the driving lever 30 even outside the vehicle by the position of the driving lever 30.
The safety seat body 12 has one of the above-described drive levers 30. Since the user can simultaneously operate the first and second locking units 40 and 40' by operating only one driving lever 30, only one driving lever 30 may be provided at the center of the front surface of the safety seat main body. Although not shown in the drawings, the driving lever 30 has a lever elastic member. The lever elastic member applies an elastic force to the driving lever 30 to return the driving lever to the home position, and provides the driving lever 30 with an elastic force acting in the direction of the safety seat body 12. Of course, the lever elastic member may be omitted.
As shown in fig. 3 and 4, a pair of guide blocks 31 are provided at one side of the driving lever 30. The guide block 31 is disposed adjacent to the driving lever 30 and guides a first wire W1 and a second wire W2 to be described below. The first and second wires W1 and W2 pass through the pair of guide blocks 31 and are coupled to the driving lever 30, respectively, so that the first and second wires W1 and W2 can be pulled or returned to the home position along a certain path.
The safety seat main body 12 has a swivel base 33. The swivel base 33 protrudes from the bottom surface of the safety seat main body 12, and a swivel assembly (not shown) for swiveling the seat part 100 may be rotatably coupled to the swivel base 33. That is, the swivel base 33 is a portion that becomes the center of rotation of the seat portion 100.
The rotating base 33 forms a moving path of the first wire W1 and the second wire W2. The first wire W1 and the second wire W2 are connected to the driving lever 30 and a first locking unit 40 and a second locking unit 40' to be described below, and move around the rotation base 33. Therefore, the moving paths of the first wire W1 and the second wire W2 are switched with respect to the rotating base 33. The first wire W1 and the second wire W2, which extend side by side in the above-described direction of the rotary base 33 from the drive lever 30, extend around the rotary base 33 in opposite directions to each other and extend in the direction of the first locking unit 40 and the second locking unit 40', respectively. To explain with reference to fig. 4, the first wire W1 extends in a counterclockwise direction around the pivotal base 33 and toward the lower portion with reference to the drawing, and the second wire W2 extends in a clockwise direction around the pivotal base 33 and toward the upper portion with reference to the drawing.
At this time, the outer surface of the rotating base 33 has positions corresponding to the first locking unit 40 and the second locking unit 40'. As shown in fig. 4, one side end (leftmost side in the drawing) of the rotating base 33 is positioned on an imaginary extension line connecting the first locking unit 40 and the second locking unit 40'. Thus, the paths of the first and second wires W1 and W2 extending around the rear of the rotating base 33 may coincide with the operating directions of the first and second locking units 40 and 40'. With this structure, the tension applied to the first wire W1 and the second wire W2 is reduced, with the result that the force for operating the drive lever 30 can be reduced.
The safety seat body 12 has a pair of setting guides 37. The above-described setting guide 37 is used to set the first locking unit 40 and the second locking unit 40', which are symmetrical to the safety seat main body 12. The installation guide 37 has a structure that surrounds the first locking unit 40 and the second locking unit 40 'in the left and right directions, respectively, but it is not limited thereto, and may have a structure that completely surrounds and shields the first locking unit 40 and the second locking unit 40', and may be omitted.
The safety seat body 12 has an entrance guide 39. The entrance and exit guide 39 is provided on a path along which the first and second fixing bodies 50 and 50 'move, and functions to guide the movement of the first and second fixing bodies 50 and 50'. For this, the access guide 39 is elongated along the moving direction of the first and second fixing bodies 50 and 50'.
As shown in fig. 5, the wire guide 38 is provided near the setting guide 37. The wire guide 38 guides the first wire W1 and the second wire W2, and guides the ends of the first wire W1 and the second wire W2 through diverged portions.
The above-described safety seat main body 12 has locking units 40, 40'. The locking units 40 and 40 ' are a pair, and for convenience of description, they are divided into a first locking unit 40 and a second locking unit 40 ', and the locking units 40 and 40 ' located relatively lower are referred to as the first locking unit 40 with reference to the drawings. The first and second locking units 40 and 40' are respectively connected to the driving lever 30 and operate simultaneously. The first and second locking units 40 and 40 'function to control the movement of the first and second fixing bodies 50 and 50'.
The first and second locking units 40 and 40 ' move in a direction perpendicular to the moving direction of the first and second fixing bodies 50 and 50 ', respectively, and selectively catch and fix a portion of the first and second fixing bodies 50 and 50 '. That is, the first and second locking units 40 and 40' are moved in a direction to approach or separate from each other by the operation of the driving lever 30.
When the first locking unit 40 is viewed, the locking housing 41 of the first locking unit 40 forms a skeleton thereof. As shown in fig. 5 and 6, the lock housing 41 has a substantially rectangular parallelepiped shape and is fixed to the setting guide 37 explained above. The lock housing 41 has an inner space formed therein in the longitudinal direction of the installation guide 37.
The lock housing 41 has a lock main body 43. The locking body 43 is movably disposed in the inner space of the locking housing 41, and is connected to the first wire W1 to be operated by the driving lever 30. The lock body 43 moves in the longitudinal direction of the lock case 41 by the first wire W1 to selectively hook and fix the first fixing body 50. In the present embodiment, the locking body 43 is substantially in the shape of a hexahedron, but is not limited thereto. Reference numeral 42 denotes a fixing boss for fixing.
The lock body 43 has a hooking head 45. The hitching head 45 is formed at the most distal end portion of the projection of the locking body 43, and may be regarded as a part of the locking body 43. The hitching head 45 is a portion inserted into a locking hole 51' formed in the first fixing body 50. The hitching head 45 is inserted into any one of a plurality of locking holes 51' formed in the first fixing body 50, and prevents the first fixing body 50 from protruding from the safety seat body 12. That is, the first fixing body 50 is in a state where the elastic force is applied by the compressed main elastic member 52 (refer to fig. 7), however, since the hooking head 45 of the locking body 43 is inserted into the locking hole 51' to hook the first fixing body 50, the first fixing body 50 does not protrude.
At this time, the hitching leg 45 forms an inclined surface. The inclined surface is formed to be inclined toward the rear of the safety seat main body 12, which protrudes toward the first fixing body 50. Due to the inclined surface, the first fixing body 50 can move so that the hitching section 45 does not get caught in the locking hole 51' while being inserted into the safety seat body 12. When the first fixing body 50 is inserted into the safety seat body 12, the inclined surface of the hitching head 45 is pressed by the edge of the locking hole 51 'to naturally retract the locking body 43, and the hitching head 45 is separated from the locking hole 51' in the process. In this case, the first fixing body 50 is in a state of being movable into the safety seat body 12. Therefore, in the present invention, it is not necessary to separately operate the driving lever 30 in the process of moving the first fixing body 50 into the interior of the safety seat body 12.
Although not shown in the drawings, the first locking unit 40 has a locking elastic member. The locking elastic member applies an elastic force to the locking body 43 in the direction of the first fixing body 50. Therefore, if the force for pulling the driving member is removed, the first locking body 43 is moved in the direction of the first fixing body 50 by the elastic force of the locking elastic member to insert the hitching head 45 into the locking hole 51'.
Next, the fixing bodies 50 and 50' will be described. The fixing bodies 50 and 50 ' are a pair, and for convenience of description, they are divided into a first fixing body 50 and a second fixing body 50 ', and the fixing bodies 50 and 50 ' located relatively at the lower part are referred to as the first fixing body 50 with reference to the drawings.
The first and second fixing bodies 50 and 50' are inserted into and removed from the safety seat body 12, and can be engaged with or disengaged from an anchor of the car seat. Wherein the anchor is located behind the rear seat of the automobile and is difficult to be identified by naked eyes at ordinary times. Thus, the first and second fixing bodies 50 and 50' need to protrude and be inserted to a certain extent rearward of the seat to be hooked to the anchor. In the present invention, the first and second fixing bodies 50 and 50' can be automatically protruded by operating the driving lever 30, so that the work of fixing to the anchor can be easily performed.
At least a portion of the first and second fixing bodies 50 and 50' is inserted into the housing 20 having the safety seat body 12. Further, the movement of projecting in the seat direction of the automobile or reversing backward is realized by the entrance guide 39 provided in the safety seat body 12. Fig. 4 shows a state where the above-described case 20 is omitted.
Since the first fixing body 50 and the second fixing body 50' have the same structure, the first fixing body 50 will be described as a standard. The first fixing body 50 has a skeleton formed by a bar-shaped moving frame 51, and the moving frame 51 is elongated in the moving direction of the first fixing body 50. The first fixing body 50 includes a coupling portion 53 protruding rearward of the safety seat body 12, and a distal end of the coupling portion 53 has a detachable end 55. The detaching end 55 is a portion fixed to the anchor, and although not shown, a latch structure is rotatably provided to the detaching end 55. The latch structure engages and disengages the anchor. The above-described latch structure can be operated by the operation button 57 of the first fixing body 50. The latch structure and the linkage of the operation button 57 are common structures, and thus a detailed description thereof is omitted.
A main elastic member 52 is connected to the first fixing body 50. The main elastic member 52 functions to give an elastic force to the first fixing body 50, and has one end fixed to the inside of the housing 20 and the other end connected to the first fixing body 50. When the first fixing body 50 is inserted into the safety seat body 12, the main elastic member 52 is compressed and the first locking unit 40 releases the fixed state of the first fixing body 50, and the main elastic member 52 is loosened and pushes the first fixing body 50 with force.
The moving frame 51 of the first fixing body 50 is formed with a plurality of locking holes 51'. The locking holes 51' are provided in plurality at regular intervals along the length direction of the moving frame 51, whereby the degree of protrusion of the first fixing body 50 can be gradually adjusted.
Hereinafter, a procedure of the operation of the fixing device of the safety seat according to the present invention will be described with reference to the accompanying drawings.
First, a user mounts the safety seat to a seat of the automobile. After the bottom surface of the safety seat, i.e., the safety seat body 12 is lowered in such a manner as to contact the upper surface of the seat, an adjustment process of centering the safety seat body 12 in the seat is then performed. At this time, the first and second fixing bodies 50 and 50' constituting the fixing device of the above-described safety seat are both in a state of being inserted into the inside of the safety seat main body 12, and the main elastic member 52 is compressed. The above state is shown in fig. 7.
In the above state, when the driving lever 30 is pulled, the driving lever 30 moves in a direction away from the safety seat main body 12 (see arrow ① direction of fig. 4). at this time, the user needs to overcome the elastic force of the lever elastic member, and when the first locking unit 40 and the second locking unit 40' have the locking elastic members, respectively, the driving lever 30 is pulled, and the locking elastic members are also elastically deformed.
When the driving lever 30 is pulled, the first wire W1 and the second wire W2 connected to the driving lever 30 are moved in the direction of the driving lever 30 (see the arrow ② direction of fig. 4). after the first wire W1 and the second wire W2 are wound around the rotary base 33, the extension directions are reversed, and thus, the opposite ends W1 ', W2' of the first wire W1 and the second wire W2 are pulled in the direction of approaching each other (see the arrow ③ direction of fig. 4).
At this time, the paths of the first and second wires W1 and W2, which extend around the rotating base 33, coincide with the operating directions of the first and second locking units 40 and 40', and thus the tension applied to the first and second wires W1 and W2 is reduced, with the result that the force for operating the driving lever 30 can be reduced.
If the first and second wires W1 and W2 move, the first and second locking units 40 and 40' connected to the first and second wires W1 and W2, respectively, operate. More precisely, as the locking body 43 moves from the locking housing 41, the hooking head 45 disengages from the locking hole 51'. The first and second locking units 40 and 40 'are hooked to the first and second fixing bodies 50 and 50', respectively, and thus the fixed states can be simultaneously released.
In addition, the main elastic member 52 is relaxed and pushes the first and second fixing bodies 50 and 50' with force to protrude the fixing bodies. The above state is shown in fig. 8. The first and second fixing bodies 50 and 50', which are strongly protruded, move in the anchor direction of the seat inner side and can be in contact with the anchor. Finally, the user presses the operation button 57 to operate the latch structure, and the detaching ends 55 of the first and second fixing bodies 50 and 50' are hooked to the anchors, thereby achieving the firm fixation.
In this manner, in the present invention, the pair of fixing bodies 50, 50' can be simultaneously protruded to reach the anchor provided to the car seat by only one operation of the driving lever 30 provided to the front of the safety seat, so that the working efficiency can be greatly improved. In particular, since the user does not need to separately manipulate the fixing bodies 50 and 50' of the fixing device, which are located inside the vehicle, the work of fixing the safety seat in a narrow vehicle interior can be facilitated.
On the other hand, the work of separating the safety seat from the seat of the automobile may be performed in the reverse manner. When the user presses the operation button again and operates the latch mechanism, the detaching end 55 is released from the anchor, and the safety seat is pulled as a whole away from the seat in this state, and the safety seat and the seat are separated.
For convenience of storage or movement, the user may also reinsert the first and second fixing bodies 50 and 50 'into the interior of the safety seat body 12, which may be accomplished simply by pushing the first and second fixing bodies 50 and 50'. Of course, when the first and second fixing bodies 50 and 50' are pushed, although the elastic force of the main elastic member 52 needs to be overcome, the driving lever 30 or another structure does not need to be operated. This is because, while the first and second fixing bodies 50 and 50 ' are inserted into the safety seat body 12, the inclined surface of the hooking head 45 is pressed by the edge of the locking hole 51 ' to naturally retract the locking body 43, and in the process, the hooking head 45 is disengaged from the locking hole 51 '. In this case, the first fixing body 50 is in a state of being movable into the safety seat body 12.
When the user pushes the first and second fixing bodies 50 and 50 'sufficiently and then removes the force, the hitching section 45 of the locking body 43 constituting the locking unit 40 or 40' is automatically inserted into the locking hole 51 'by the elastic force of the locking elastic member, and thus the first and second fixing bodies 50 and 50' do not protrude again and can maintain the fixed state.
