DETAILED DESCRIPTION
FIG. 1 shows a front perspective view illustrating the main components of a car seat according to an embodiment of the present invention. The car seat 10 includes a main body 12 having an approximately horizontal seat portion 14 joined to an approximately vertical back portion 16. A headrest 18 is joined to the back portion 16 of the body 12 and can be adjusted, as explained below. Armrests 20 can be removably affixed to the back portion 16 of the body 12. A cupholder 22 can be removably affixed to the seat portion 14 of the body 12. The car seat 10 can be covered with padding to provide cushioning, as depicted in FIG. 1.
The headrest 18 can be manually adjusted by the user to accommodate infants of different heights. FIG. 2 shows a close-up view of the headrest 18. The headrest 18 includes a headrest panel 24 contoured for supporting the head of an infant, and a lever 26. The lever 26 has a prong 28 that engages the seat body 12, as explained below. The lever 26 is joined to the headrest panel 24 at two pivot points 30 such that the lever 26 can rotate about an axis defined by the pivot points. Tabs 34 on the headrest panel 24 hold the lever 26 in place, allowing a narrow range of rotation. Spring 36, which is located between the headrest panel 24 and the lever 26, provides restoring force to bias the lever such that its prong 28 is normally in the extended position.
FIG. 3 shows the headrest 18 joined to the seat body 12. The headrest 18 is held in place by flanges 38 (shown on the headrest in FIG. 2), allow the headrest to slide in a vertical direction relative to the seat body 12. The top view of FIG. 4 illustrates how these flanges 38 on the headrest 18 fit into tracks 41 in the seat body. The flanges 38 are held into these tracks 41 by flanges 39 on the seat body 12. The headrest 18 is therefore joined to the seat body 18 and cannot move horizontally (i.e. perpendicular to the flanges 38 and the flanges 39) with respect to the seat body 12, but the headrest 18 can slide vertically (i.e. parallel to the flanges 38 and the flanges 39) with respect to the seat body 12.
Returning to FIG. 3, the headrest can be adjusted by the user to assume one of a plurality of different height positions. The seat body 12 contains a plurality of semicylindrical pockets 42, 43, 44, and 45 for engaging the prong 28 of the lever 26, locking the headrest 18 in place. The headrest 18 can be adjusted to different positions (i.e. a different height above the seat portion 14 of the car seat 10) depending on which pocket the ridge 28 is engaged with. These possible positions for the headrest, which are determined by the number and spacing of the pockets, can be referred to as the “discrete positions.”
In FIG. 3, the headrest is shown in the retracted (down) position. The prong 28 on the lever 26 is engaged with the bottom pocket 45 on the seat body 12. In order to adjust the headrest and put it into another one of the discrete positions, the user actuates the handle 40 on the lever 26 by squeezing the handle 40 and the headrest 18 together. This action forces the lever to rotate about the axis defined by its attachment points 30, and the handle 40 on the lever 26 moves closer to the headrest panel 24 as the angle between the plane defined by the lever 26 and the plane defined by the headrest panel 24 becomes smaller. This rotation of the lever 26 causes the prong 28 to become disengaged with the pockets, allowing the headrest 18 to slide vertically with respect to the seat body 12. The user can then slide the headrest to the desired position. When the headrest is positioned such that the prong 28 is over one of the pockets, the user can release the handle 40 on the lever 26. The spring 36 will restore the lever to its normal position, and the prong 28 will engage with the pocket, thus locking the headrest 18 into position. FIG. 5 shows the headrest in the extended (up) position, with the prong 28 engaged with the top pocket 42 on the seat body 12.
In an embodiment of the present invention, the car seat can include removable armrests. FIGS. 6 and 7 show an armrest 20, which can be joined to the seat body 12 at opening 50. The armrest 20 includes an arm portion 52 and a mounting portion 54. The arm portion 52 can be rotated about the mounting portion 54 above the horizontal plane, so that the arm portion can be raised as shown in FIG. 7. The mounting portion 54 has an attachment fairing 56 that fits into the opening 50 on the seat body 12. The attachment fairing 56 includes a locking tab 58 with a flange 60 that locks the armrest in place when joined to the seat body. When the attachment fairing 56 is inserted into the opening 50, the flange 60 will fit between the top edge 59 of the opening 50 and the release lever 61, both of which hold the locking tab 58 in place.
FIG. 8 shows the armrest 20 joined to the seat body 12. The attachment fairing 56 has been inserted into the opening 50 in the seat body 12, and the flange 60 on the locking tab 58 is engaged with the top edge 59 of the opening 50 such that the armrest in locked in place. The user can remove the armrest by pressing downward on the release lever 61 and the locking tab 58 so that the flange 60 is no longer engaged with the top edge 59 of the opening 50, thus permitting the attachment fairing 56 to slide out of the opening 50.
In an embodiment of the present invention, the car seat can include a removable folding cup holder. FIG. 9 shows a removable cupholder 22 that can be attached to the car seat 10. The cup holder 22 has a clip 62 that can fit into slot 64 on the seat body 12, thus allowing the cup holder to be attached to the seat body, as shown in FIG. 10. The cup holder can be unfolded, allowing it to accept a cup, as shown in FIG. 11.
The cup holder 22 includes a body 66, a cover 68, and a ring 70. The cover 68 is joined to the body 66 at points 72. The cover 68 can rotate about the axis formed by points 72, allowing it to rotate from the closed position depicted in FIGS. 9 and 10 and the open position depicted in FIG. 11, where the cover is horizontal. A nub 74 on the cover 68 near each attachment point 72 prevents the cover from rotating below the horizontal plane. The ring 70 is joined to the body 66 at points 76, allowing it to rotate upward from the vertical stowed position to the horizontal position depicted in FIG. 11. Upon reaching the horizontal position, tabs 78 on the ring 70 are engaged by flanges 80 on the body 66, thus holding the ring in the horizontal position. The flanges 80 are molded on flexible tabs so that they can allow tabs 78 to become disengaged if the user applies sufficient downward force to the ring 70, thus allowing the ring to be restored to its vertical stowed position by the user.
