Description

INFANT CAR SEAT
Background of the Invention
1. Field of the Invention
The present invention relates to an infant car seat, and more particularly, to an anti-falling infant car seat.
2. Description of the Prior Art
When riding in a vehicle, an infant should sit in an infant car seat installed on a car seat instead of sitting on the car seat directly due to safety concern. An infant car seat can be installed on a car seat of a car forwardly or rearwardly according to practical demands. When the infant car seat is located at a forward position, an infant sitting in the infant car seat faces forward. When the infant car seat is located at a rearward position, the infant faces a backrest of the car seat. However, when a traffic accident occurs and the car receives an impact, the rearward infant car seat may fall over toward the car seat, which may harm the infant.
In order to prevent the rearward infant car seat from falling over, the European Patent No. EP751035 discloses an infant car seat with an anti-rebound component. The anti-rebound component is disposed under the infant car seat and for abutting against the backrest of the car seat, so as to support the infant car seat stably. Therefore, it effectively prevents the infant car seat from falling over rearwardly.
However, there is no use of the anti-rebound component when the infant car seat is located at the forward position. The anti-rebound component should be folded when the infant car seat is switched from the rearward position to the forward position, which is not convenience in use.
Therefore, in order to enhance safety and convenience, there is a need to provide an infant car seat which is capable 5 of preventing from falling over without an anti-rebound component.
Summary of the Invention
It is an objective of the present invention tc provide 10 an infant car seat which is capable of preventing from falling over without an anti-rebound component.
In order to achieve aforementioned objective, the present invention discloses an infant car seat detachably installed on a car seat of a car. The infant car seat includes a base and a body. The base is formed in a wedge shape. A thickness of a rear end of the base is greater than a thickness of a front end of the base. An abutting rod is disposed on the front end of the base and extends downwardly for supporting the base above a ground of the car. The body is rotatably disposed on the base and switchable between a forward position and a rearward position relative to the base. A rear surface of the body abuts against a backrest of the car seat when the body is located at the forward position, and a front edge of the body abuts against the backrest of the car seat when the body is located at the rearward position.
Preferably, an inclined angle between an upper surface and a lower surface of the base is 15 degrees.
Specifically, the front edge of the body and the rear end of the base are substantially aligned with each other in a vertical direction when the body is located at the rearward position.
Preferably, the front edge of the body includes two arc-shaped structures connecxed with each other, and two middle portions of the two arc-shaped structures are bent 5 downwardly.
Preferably, an acute angle is included between an extending line of the rear surface of the body and an upper surface of the car seat when the body is located at the rearward position. The body is swingable relative to the base for adjusting the acute angle, and a motion path of the front edge of the body is formed in an arc shape during swinging operation of the body relative to the base.
Specifically, the acute angle is substantially from 36 to 42 degrees.
Specifically, at least one front sliding slot and at least one rear sliding slot are formed on the front end and the rear end of the base respectively. Each of the at least one front sliding slot and the at least one rear sliding slot is formed in an arc shape with two upward ends. A front rod and a rear rod are disposed on a bottomportion of the base, and the front rod and the rear rod are slidably disposed within the at least one front sliding slot and the at least one rear sliding slot respectively when the body is supported on the base.
More specifically, two front erecting plates are disposed on two sides of the front end of the base. Two front sliding slots are formed on the two front erecting plates. Two rear erecting plates are disposed on two sides of the rear end of the base. Two rear sliding slots are formed on the two rear erecting plates. Two ends of the front rod are located within the two front sliding slots, and two ends of the rear rod are located within the two rear sliding slots.
Furthermore, the infant car seat further includes a locking mechanism disposed on the bottom portion of the body and located between the two front erecting plates. The locking mechanism includes an operating component slidable relative to the body, at least one engaging component, and a linking component fixed on the body. The two ends of the front rod passes through the linking component to stretch into the two front sliding slots. A plurality of engaging holes is formed on at least one of the two fron:, erecting plates. The at least one engaging component passes through the linking component to engage with at least one of the plurality of engaging holes when the operating component slides toward the body, and the at least one engaging component disengaging from the at least one of the plurality of engaging holes when the operating component slides away from the body.
Preferably, a first distance is defined between the front edge of the body and an upper surface of the car seat when the body is located at the forward position. A second distance is defined between the front edge of the body and the upper surface of the car seat when the body is located at the rearward position, and a ratio of the first distance to the second distance is substantially from 0.4 to 0.6.
Specifically, the first distance is 148 mm.
Specifically, the second distance is greater than or equal 30 to 265 mm.
Preferably, a second distance is defined between the front edge of the body and an upper surface of the car seat when the body is located at the rearward position. A third distance is defined between a handrail of the body and the upper surface of the car seat, and a ratio of the second distance to the third distance is substantially from 0.6 to 0.8.
Specifically, the second distance and the third distance are 265 mm and 375 mm respectively.
In summary, the infant car seat of the present invention abuts against the ground and the backrest at the same time no matter when the body is located at the forward position or the rearward position. Therefore, a front end and a rear end of the infant car seat can be supported stably. Furthermore, when the body is located at the rearward position, the front edge of the body abuts against the backrest of the car seat, which effectively prevents the infant car seat from falling over and enhances safety of the infant car seat. Therefore, no conventional anti-rebound component is necessary for the infant car seat of the present invention, which has advantages of simple structure and easy operation.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

Please refer to FIG. 1 to FIG. 5. FIG. 1 is a schematic diagram of an infant car seat 1 according to an embodiment of the present invention. FIG. 2 is a perspective diagram of the infant car seat 1 installed on a car seat 2 as a body 12 is located at a forward position according to the embodiment of the present invention. FIG. 3 is a lateral view of the infant car seat 1 installed on the car seat 2 as the body 12 is located at the forward position according to the embodiment of the present invention. FIG. 4 is a perspective diagram of the infant car seat 1 installed on the car seat 2 as the body 12 is located at a rearward position according to the embodiment of the present invention. FIG. 5 is a lateral view of the infant car seat 1 installed on the car seat 2 as the body 12 is located at the rearward position according to the embodiment of the present invention. As shown in FIG. 1 to FIG. 5, the infant car seat 1 is detachably installed on the car seat 2 of a car to provide protection for an infant sitting therein. The infant car seat 1 includes a base 11 and the body 12. The body 12 is rotatably disposed on the base 11 for the infant to sit in. After the infant car seat 1 is installed on the car seat 2, the body 12 can rotate relative to the base 11 to the forward position, as shown in FIG. 2, or to the rearward position, as shown in FIG. 4. The infant sitting in the body 12 faces forward when the body 12 is located at the forward position. The infant sitting in the body 12 faces a backrest 21 of the car seat2 when the body 12 is located at the rearward position.
The base 11 is formed in a wedge shape, and a thickness of a rear end of the base 11 is greater than a thickness of a front end of the base 11. A lower surface of the base 11 is substantially parallel to a horizontal direction. An inclined angle a is formed between an upper surface and the lower surface of the base 11. In this embodiment, the inclined angle a can preferably be 15 degrees. An abutting rod 13 is disposed on a front end of the base 11 and extends downwardly for supporting the base 11 above a ground of the car. In this embodiment, the abutting rod 13 can be a retractable structure, which can be adjusted according to a height of the car seat 2 for keeping abutting against the ground of the car. Two connecting arms 14 are disposed on a rear end of the base 11 and extend rearwardly for engaging with two corresponding ISOFIX connectors, which are not shown in figures, disposed on the car seat 2, so as to fix the infant car seat 1 on the car seat 2.
The body 12 includes a back plate 121 and two lateral plates 122. The hack plate 121 is for the infant to lean on. The two lateral plates 122 are fixed on two sides of the back plate 121. Two handrails 123 are defined by two upper edges of the two lateral plates 122 and for the infant to hold. A front edge 124 of the body 12 is located between the two lateral plates 122 and includes two arc-shaped structures 124a bent downwardly and connected with each other. When the body 12 is located at the forward position, the infant can put his/her two legs on the two arc-shaped structures 124a.
As shown in FIG. 3, when the body 12 is located at the forward position, a rear surface of the back plate 121 of the body 12 can abut against the backrest 21 of the car seat 2. At this moment, a first distance H1 is defined between the front edge 124 of the body 12 and an upper surface of the car seat 2.
As shown in FIG. 5, when the body 12 is located at the rearward position, the front edge 124 is substantially aligned with the rear end of the base 11 in a vertical direction perpendicular to the horizontal direction. A second distance H2 is defined between the front edge 124 of the body 12 and the upper surface of the car seat 2. A third distance H3 is defined between the handrail 123 of the body 12 and the upper surface of the car seat 2. Since the base 11 is a wedge-shaped structure with the preferable 15-degree inclined angle a between the upper surface and the lower surface, the front edge 124 rises gradually during the period that the body 12 is switched from the forward position to the rearward position. Therefore, the second distance 112 is greater than the first distance Hl. Furthermore, when the body 12 is located at the rearward position, the front edge 124 is for abutting against the backrest 21 of the car seat 2. Since the front edge 124 includes two arc-shaped structures 124a, a contacting area of the front edge 124 and the backrest 21 is much greater than a contacting area of a straight front edge of an infant car seat and the backrest, which can generate a greater frictional force between the front edge 124 and the backrest 21 for enhancing stability of the infant car seat 1 when the body 12 abuts against the backrest 21.
Furthermore, in order to ensure the body 12 to abu" against the backrest 21 no matter when the body 12 is located at the forward pos ition or the rearward position, a ratio of The first distance H1 to the second distance H2 can be substantially 5 from 0.4 to 0.6, and a ratio of the second distance H2 to the third distance H3 can be substantially from 0.6 to 0.8. Specifically, the second distance H2 is preferably greater than or equal to 265 mm, which can ensure that the front edge 124 abuts against the backrest 21. In this embodiment, the 10 first distance H1, the second distance H2, and the third distance H3 are 148 ram, 265 mm, and 375 mm respectively.

FIG. 7 is a lateral view of the infant car seat 1 as the body 12 is located at the rearward position with the supplementary angle at 40 degrees according to the embodiment of the present invention. FIG. 8 is a lateral view of the infant car seat 1 as the body 12 is located at the rearward position with the supplementary angle 3 at 38 degrees according to the embodiment of the present invention. FIG. 9 is a lateral view of the infant car seat 1 as the body 12 is located at the rearward position with the supplementary angle p at 36 degrees according to the embodiment of the present invention. The body 12 can swing relative to the base 11 back and forth for adjusting an inclined angle of the body 12. When the body 12 is located at the rearward position, an acute angle is Included between an extending line of the back plate 121 of the body 12 and the upper surface of the car seat 2. The acute angle can be defined as the supplementary angle [3. When the body 12 becomes more and more oblique relative to the base 11, the supplementary angle p becomes smaller and smaller. In this embodiment, the supplementary angle can be preferably from 36 to 42 degrees, so as to prevent the body 12 from being excessive oblique, which reduces a risk of falling over of the infant car seat 1. As shown in FIG. 6 to FIG. 9, the supplementary angles 3 are 42, 40, 38, 36, degrees, respectively.
When the body 12 is located at the rearward position, a motion path of the front edge 124 is formed in an arc shape during swinging operation of the body 12, so as to maintain a contacting distance between the front edge 124 and the backrest 21, which ensures the front edge 124 to provide an anti-rebound effect.

A driving column 153a protrudes from an end of each of the two driving components 153 away from the corresponding lateral portion 151a. A positioning slot 153b is formed on another end of each of the two driving components 153 near the corresponding lateral portion 151a. Each of the two engaging components 154 is formed in a U shape. Middle portions of the two engaging components 154 are received in the two positioning slots 153b of the two driving components 153 respectively. Two arm portions of each of the two engaging components 154 pass through the two lower through holes 151c on the corresponding lateral portion 151a to engage with the corresponding engaging holes 112b on the corresponding front erecting plate 112. When the two engaging components 154 engage with the corresponding engaging holes 112b, the linking component 151 is locked relative to the base 11. Therefore, the body 12 cannot swing relative to the base 11.
The operating component 152 is disposed on the bottom portion of the body 12 and slidahle relative to the body 12 along the front-back direction of the infant car seat 1. In this embodiment, the operating component 152 can be a handle. A guiding slot 152a and two driving inclined slots 152b are formed on a rear end of the operating component 152. The two driving inclined slots 152b are located at two sides of the guiding slot 152a. The guiding column 151e is located within the guiding slot 152a, so as to restrain a sliding direction of the operating component 152 relative to the body 12. The two driving inclined slots 152b are located above the two driving components 153. The two driving columns 153a of the two driving components 153 pass through the two driving inclined slots 152b. When the operating component 152 slides toward the body 12, the two driving components 153 are driven to slide outwardly by cooperation of the two driving inclined slots 152b and the two driving columns 153a, so that the two engaging components 154 are driven to pass through the two lateral portions 151a to engage with the corresponding engaging holes 112b, which locks the linking component 151. When the operating component 152 slides away from the body 12, the two driving components 153 are driven to slide inwardly, so that the two engaging components 154 are retracted to disengage from the corresponding engaging holes 112b, which releases the linking component 151. When the linking component 151 is released, the body 12 and the locking mechanism 15 are allowed to swing relative to the base 11 together. After the body 12 and the linking component 151 swings relative to base 11 by an predetermined angle, the operating component 152 can be operated to slide toward the body 12 to drive the two engaging components 154 to engage with other engaging holes 112b, so as to lock the body 12 and the linking component 151 again.
The locking mechanism 15 further includes a first recovering spring 155 and two second recovering springs 156. A positioning column 152c protrudes from the operating component 152. In this embodiment, the first recovering spring 155 can be a tensional spring. Two ends of the first recovering spring 155 are connected to the guiding column 151e and the positioning column 152c. The first recovering spring 155 biases the operating component 152 to slide toward the body 12 for locking the linking component 151 and the body 12. Each of the two second recovering springs 156 is disposed between the corresponding driving component 153 and the linking component 151. The two second recovering springs 156 bias the two driving components 153 to move outwardly for driving the two engaging components 154 to engage with the corresponding engaging holes 112b.
