1. An infant car seat comprising:a seat shell; and a handle comprising a generally triangular grip portion and a pair of handle arms extending generally perpendicular from said grip portion, each of said handle anus being rotatably connected to said seat shell at an end of said handle arm opposite said grip portion, wherein said grip portion comprises a first grip section extending generally perpendicular to a central longitudinal axis of said seat shell, a second grip section and a third grip section, said second and third grip sections extending inwardly towards said central longitudinal axis from opposite ends of said first grip section. 2. The car seat of claim 1, wherein said handle arms extend from said ends of said first grip section.3. An infant car seat comprising:a seat shell; and a handle comprising a grip portion and a pair of handle arms extending from said grip portion, each of said handle arms being rotatably connected to said seat shell at an end of said handle arm opposite said grip portion, said grip portion comprising a first grip section extending generally perpendicular to a central longitudinal axis of said seat shell, a second grip section and a third grip section, said second and third grip sections extending inwardly towards said central longitudinal axis from opposite ends of said first grip section. 4. The car seat of claim 3, wherein said third grip section extends at an angle α with respect to said central longitudinal axis of approximately 30 degrees and said second grip section extends at an angle β with respect to said central longitudinal axis of approximately 330 degrees.5. The car seat of claim 3, wherein said first, second and third grip sections are approximately the same length.6. The car seat of claim 3, wherein each of said handle arms comprises a first arm portion extending forwardly from said grip portion towards a head of said seat shell when said handle is positioned so that said grip portion is above said seat shell, a second arm portion extending rearwardly from said first arm portion, and a third arm portion extending forwardly from said second arm portion.7. An infant car seat, comprising:a seat shell; a handle comprising a grip portion and a pair of handle arms extending from said grip portion, each of said handle arms being rotatably connected to said seat shell at an end of said handle arm opposite said grip portion; and a handle lock mechanism associated with at least one of said handle arms, said handle lock mechanism comprising: a latch slidably connected to said at least one handle arm, said latch comprising a tab extending towards said seat shell such that said tab points in a direction that intersects a plane in which said handle arms rotate; a plurality of locking surfaces associated with said seat shell; an actuator operable to slide said latch between a first position wherein said tab interferes with said locking surfaces to prevent rotation of said handle with respect to said seat shell, and a second position wherein said tab does not interfere with said locking surfaces and said handle is allowed to rotate with respect to said seat shell; and a biasing member biasing said latch towards said first position. 8. The car seat of claim 7, wherein said lock mechanism further comprises a position stamping connected to said seat shell, and said locking surfaces comprise notches formed in a perimeter of said position stamping.9. The car seat of claim 8, wherein said tab extends into one of said notches when said latch is in said first position.10. The car seat of claim 7, wherein a portion of said latch extends into a recess formed in said at least one handle arm, and said biasing member comprises a coil spring located in said recess, said coil spring applying a force on said portion of said latch extending into said recess to bias said latch towards said first position.11. The car seat of claim 7, wherein said actuator comprises a cam surface that extends into a pocket formed in said at least one handle arm.12. The car seat of claim 11, further comprising a follower associated with said latch, said follower moving across said cam surface when said actuator is operated, causing said latch to move from said first position to said second position.13. The car seat of claim 7, wherein said grip portion comprises a first grip section extending generally perpendicular to a central longitudinal axis of said seat shell, a second grip section and a third grip section, said second and third grip sections extending inwardly towards said central longitudinal axis from opposite ends of said first grip section.14. An infant car seat comprising:a seat shell; a handle rotatably connected to said seat shell; and a handle lock mechanism, comprising: a position stamping connected to said seat shell; a latch slidably connected to said handle, said latch comprising a tab extending towards said seat shell such that said tab points in a direction that intersects a plane in which said handle arms rotate; a biasing member biasing said latch towards a first position wherein said tab cooperates with said position stamping to prevent rotation of said handle relative to said seat shell; and an actuator operable to slide said latch to a second position wherein said tab is moved away from said position stamping and said handle is allowed to rotate relative to said seat shell. 15. The car seat of claim 14, wherein said position stamping comprises a plurality of notches formed in a perimeter thereof, said tab extending into one of said notches when said latch is in said first position.16. The car seat of claim 14, wherein a portion of said latch extends into a recess formed in said handle, and said biasing member comprises a coil spring located in said recess, said coil spring applying a force on said portion of said latch extending into said recess to bias said latch towards said first position.17. The car seat of claim 14, wherein said actuator comprises a cam surface that extends into a pocket formed in said handle.18. The car seat of claim 17, further comprising a follower associated with said latch, said follower moving across said cam surface when said actuator is operated, causing said latch to move from said first position to said second position.19. An infant car seat comprising:a seat shell; and a handle comprising a triangular grip portion and a pair of handle arms extending from said grip portion, said triangular grip portion having a first side, a second side, and a third side, the first side being connected to the second side and the third side, the second side being connected to the first side and the third side, and the third side being connected to the first side and the second side, each of said handle arms being rotatably connected to said seat shell at an end of said handle arm opposite said grip portion. 20. The car seat of claim 19, wherein said first side is positioned generally perpendicular to a central longitudinal axis of said seat shell, and said second side and said third side extend inwardly towards said central longitudinal axis from opposite ends of said first side.21. The car seat of claim 19, wherein said first side, said second side, and said third side are in one plane.22. An infant car seat comprising:a seat shell; a handle rotatably connected to said seat shell; and a handle lock mechanism, comprising: a position stamping having a generally planar portion connected to said seat shell; a latch slidably connected to said handle, said latch comprising a tab extending towards said position stamping; a biasing member biasing said latch towards a first position wherein said tab cooperates with said position stamping to prevent rotation of said handle relative to said seat shell; and an actuator operable to slide said latch to a second position wherein said tab is moved away from said position stamping and said handle is allowed to rotate relative to said seat shell. 23. The infant car seat of claim 22, wherein planar portion of the position stamping has a plurality of notches, and in said first position, the tab sits within one of said notches.24. The infant car seat of claim 22, wherein the generally planar portion has a generally circular perimeter.25. The infant car seat of claim 24, wherein the generally planar portion has a plurality of notches.26. The infant car seat of claim 25, wherein in said first position, said tab sits within one of said notches.27. The infant car seat of claim 24, wherein in said second position the tab abuts the generally circular perimeter of the generally planar portion.
