To transition the device into a stroller, the handle is extended, and the front wheels and the rear wheels are extended or unfolded to function as conventional stroller wheels wherein a sunshade is detachably attached to the frame of the device. The front wheels are supported by a pivotable front wheel leg and the rear wheels are supported by a pivotable rear wheel leg.

[0023] Referring initially to the drawings, FIG. 1 illustrates a side elevation view of a convertible car seat of the present invention in accordance with the disclosed structure. FIG. 1 shows only one side of the convertible car seat 100, however, most components include a complementary component on the opposite side of the convertible car seat 100 but are not shown in FIG. 1. The convertible car seat 100 is configured to have a transition between the car seat orientation as illustrated in FIG. 1 to a stroller orientation as illustrated in FIG. 3.

[0024] The convertible car seat 100 includes a seat frame 102 for supporting a seat 104. The seat 104 can be permanently affixed to the frame 102 or releasably connected, such that it is capable of being removed and substituted with a different seat. The seat 104 has a rearwardly inclined back portion 106 for supporting a back of a child sitting in the car seat 100 and has a front portion 108 for supporting the bottom and legs of the child.

[0025] The convertible car seat 100 includes a pivotable handle 110 having a grip portion 112 and is positioned along the frame 102 to circumscribe the back portion 106 of the seat 104. The handle 110 is pivotable and includes the handle pivoting control 114 for pivoting the handle 110. For securing a child in the car seat 100, a seat belt 116 is provided which can be fastened using any conventional fastener such as a buckle 118 as illustrated in FIG. 5. The handle 110 is in a retracted position and is positioned along the top of the frame 102 when the device 100 is in a folded state to be used inside a vehicle as illustrated in FIGS. 1-3.

[0026] The combined stroller and car seat device 100 has a pair of front wheels 120 and a pair of rear wheels 122, the front wheels 120 have colinear left wheel and right wheel and the rear wheels 122 include colinear left wheel and right wheel. The front wheels 120 are attached to the frame 102 using front wheel leg 124, and the rear wheels 122 are attached to the frame 102 using rear wheel leg 126. In the car seat orientation as illustrated in FIG. 1, the front wheel leg 124 and the front wheels 120 are accommodated along the horizontal portion 128 of the frame 102. Similarly, the rear wheels 122 and the rear wheel leg 126 are accommodated along the inclined portion 130 of the frame 102. The legs 124, 126 can be extended to convert the car seat into a stroller as illustrated in FIG. 4.

[0027] Referring to FIGS. 2 and 3, the convertible car seat 100 comes with a car seat base 132 used for securing the bottom portion 134 of the frame 102 to a vehicle's latch or belt system. The base 132 includes a pair of side grooves 136 for accommodating and securing the front wheels 120. The central portion 138 of the base 132 provides support to the car seat 100. The seat base 132 is secured to the belt system of the vehicle using harnesses or belts 140. The sides 142, 144 of the seat 104 are designed to have a first curved shape 146 for supporting and accommodating the rear wheels 122 and a second curved shape 148 for supporting and accommodating the front wheels 120. The push button 158 can be pushed to release the car seat device 100 from the base 132 for easy removal and accessibility. The base 132 can be made of any soft material and can be ergonomic for securing the convertible car seat 100 in both rear-facing and front-facing positions.

[0028] FIG. 4 illustrates a side elevation view of the convertible car seat in an unfolded orientation to convert into a stroller in accordance with the disclosed structure. For converting the car seat 100 into a stroller, the car seat device 100 is removed from the base 132. The handle 110 is pivotally moved to position on top of the seat 102 wherein the handle 110 can be extended to be positioned in an extended position. Then, rear wheel legs 126 are unfolded by pulling the rear wheels 122 behind the back portion 106. Each front leg 124 has a first pivoting member 150 and a second pivoting member 152 which rests above each other when front wheel 120 is folded as illustrated in FIG. 1 and pivotally extends on pulling and unfolding the front wheel 120. The second pivoting member 152 has an integrally connected arcuate member 154 which is connected to the front wheel 120. The rear wheels 122 have wheel locks 156 for restricting movement thereof and can be pulled to apply the lock or brakes.

[0029] A wheels supporting member 160 is disposed on the bottom portion 134 of the frame 102. The wheels supporting member 160 is flexible and can be stitched to the bottom portion 134 of the frame 102.
