Abstract

An infant car seat is provided, including a car seat, a car seat base, and a mechanism for connecting the seat to the base. With the car seat base secured to a vehicle seat, the car seat can be conveniently connected to the base to safely transport an infant. The connection and release mechanisms between the car seat and the base are durable and easy to operate.

Claims

1. An apparatus, comprising:

a base, comprising;

a main body; and

a connection bracket extending from said main body, said connection bracket comprising a first side wall having a first slot therein, a first pawl pivotably connected adjacent said first side wall, a biasing member biasing said first pawl towards said first slot, a second side wall spaced apart from said first side wall and having a second slot therein, a second pawl pivotably connected adjacent said second side wall, and a second biasing member biasing said second pawl towards said second slot; and

an infant car seat, comprising;

a seat shell; and

a rod extending through said seat shell, said rod extending into said first and second slots when said car seat is situated on said base, said first and second pawls extending over said rod to lock said car seat to said base.

2. The apparatus of claim 1, wherein a curved slot is provided in each of said first and second side walls for passage of a vehicle seat belt.

3. The apparatus of claim 1, said car seat further comprising a release handle movably connected to said seat shell, said release handle contacting said first and second pawls as said handle is moved to pivot said pawls away from said rod and allow said rod to be removed from said first and second slots.

4. An apparatus comprising:

a base comprising a main body and a connection bracket extending from said main body, said connection bracket comprising a first side wall having a first slot therein, a first pawl pivotably connected adjacent said first side wall, a biasing member biasing said first pawl towards said first slot, a second side wall spaced apart from said first side wall and having a second slot therein, a second pawl pivotably connected adjacent said second side wall, and a second biasing member biasing said second pawl towards said second slot; and

an infant car seat comprising a seat shell;

a rod extending through said seat shell, said rod extending into said first and second slots when said car seat is situated on said base, said first and second pawls extending over said rod to lock said car seat to said base;

a release handle movably connected to said seat shell, said release handle contacting said first and second pawls as said handle is moved to pivot said pawls away from said rod and allow said rod to be removed from said first and second slots;

a first mounting hook including a first leg and a second leg connected to said first leg, said first leg having a barb extending therefrom, said barb extending into a first recess in said seat shell;

a second mounting hook including a first leg and a second leg connected to said first leg, said first leg having a barb extending therefrom, said barb extending into a second recess in said seat shell;

a first strap connecting said release handle to said first leg of said first mounting hook; and

a second strap connecting said release handle to said first leg of said second mounting hook.

5. The apparatus of claim 4, said base further comprising a first mount and a second mount, said barbs engaging said first and second mounts when said car seat is situated on said base.

6. The apparatus of claim 5, wherein movement of said release handle causes said first and second straps to pull said first legs of said mounting hooks away from said second legs, releasing said barbs from said mounts.

7. The apparatus of claim 4, wherein said first and second mounting hooks comprise acetyl.

8. The apparatus of claim 4, wherein said first and second mounting hooks have an inverted “

V”

shape.

9. The apparatus of claim 4, wherein said release handle is slideably connected to the seat shell near the foot end.

10. An apparatus comprising:

a base, comprising;

a main body; and

a connection bracket extending from said main body, said connection bracket comprising a first side wall having a first slot therein, a first pawl pivotably connected adjacent said first side wall, a biasing member biasing said first pawl towards said first slot, a second side wall spaced apart from said first side wall and having a second slot therein, a second pawl pivotably connected adjacent said second side wall, and a second biasing member biasing said second pawl towards said second slot; and

an infant car seat, comprising;

a seat shell;

a rod extending through said seat shell, said rod extending into said first and second slots when said car seat is situated on said base, said first and second pawls extending over said rod to lock said car seat to said base; and

a release handle movably connected to said seat shell, said release handle contacting said first and second pawls as said handle is moved to pivot said pawls away from said rod and allow said rod to be removed from said first and second slots, wherein said release handle is connected to said seat shell by a pair of hooks that extend into slots in the seat shell.

11. An apparatus comprising:

a base, comprising;

a main body; and

a connection bracket extending from said main body, said connection bracket comprising a first side wall having a first slot therein, a first pawl pivotably connected adjacent said first side wall, a biasing member biasing said first pawl towards said first slot, a second side wall spaced apart from said first side wall and having a second slot therein, a second pawl pivotably connected adjacent said second side wall, and a second biasing member biasing said second pawl towards said second slot; and

an infant car seat, comprising;

a seat shell;

a rod extending through said seat shell, said rod extending into said first and second slots when said car seat is situated on said base, said first and second pawls extending over said rod to lock said car seat to said base;

a release handle movably connected to said seat shell, said release handle contacting said first and second pawls as said handle is moved to pivot said pawls away from said rod and allow said rod to be removed from said first and second slots, wherein a biasing member biases the release handle towards the head end of the seat shell.

12. An apparatus comprising a base;

and an infant car seat comprising a seat shell, wherein said seat shell is removably connected to said base through four or more connectors, and a release handle, wherein moving said release handle operates to release each of the four or more connectors, thereby allowing the seat shell to be removed from the base, wherein;

a first connector of said four or more connectors comprises a first mounting hook including a first leg and a second leg connected to said first leg, said first leg having a barb extending therefrom, wherein said barb is configured to engage a first mount on said base when the seat shell is connected to the base;

a second connector of said four or more connectors comprises a second mounting hook including a first leg and a second leg connected to said first leg, said first leg having a barb extending therefrom, wherein said barb is configured to engage a second mount on said base when the seat shell is connected to the base; and

the release handle is operably connected to said first mounting hook and to said second mounting hook such that moving the release handle causes the first leg of said first mounting hook to rotate about the point at which the first and second legs of said first mounting hook connect and causes the first leg of said second mounting hook to rotate about the point at which the first and second legs of said second mounting hook connect.

13. The apparatus of claim 12, wherein a third connector and a fourth connector of said four or more connectors each comprise a first pawl pivotably connected to said base and a biasing member biasing said pawl towards a slot in said base.
