Four locking points removably engage the seat to the base comprising two spaced apart rear locking points positioned toward the rear end of the base and two spaced apart front locking points positioned toward the front end of the base. An actuator control releases the engagement between the seat and the base. ## Claims ### Claim 1 A multi-point locking system for a carseat comprising: a base having an upper surface, a lower surface, front and rear ends, and left and right sides, the lower surface dimensioned to rest upon a vehicle seat; a seat having a seating surface and an exterior surface, the exterior surface removably engagable with the upper surface of the base; four locking points to removably engage the seat to the base comprising two spaced apart rear locking points positioned toward the rear end of the base and two spaced apart front locking points positioned toward the front end of the base; and an actuator control to release the engagement between the seat and the base. ### Claim 2 (depends on 1) The multi-point locking system of claim 1, wherein the rear locking points comprise a pair of securing latches and a complementary pair of receiving apertures. ### Claim 3 (depends on 2) The multi-point locking system of claim 2, wherein the securing latches extend from the base and the receiving apertures are defined in the exterior surface of the seat. ### Claim 4 (depends on 1) The multi-point locking system of claim 1, wherein the front locking points comprise left and right slots and a complementary pair of retractable securing projections. ### Claim 5 (depends on 4) The multi-point locking system of claim 4, wherein the left and right slots are defined in the upper surface of the base and the retractable securing projections extend from exterior surface of the seat. ### Claim 6 (depends on 1) The multi-point locking system of claim 1, wherein the actuator control is positioned on the exterior surface of the seat. ### Claim 7 A carseat comprising: a base having an upper surface, a lower surface, front and rear ends, and left and right sides, the lower surface dimensioned to rest upon a vehicle seat; a seat having a seating surface and an exterior surface, the exterior surface dimensioned to engage the upper surface of the base; a multi-point point locking system to removably engage the seat to the base comprising two vertical points of engagement between the seat and the base and two side points of engagement between the seat and the base; and an actuator control to release the engagement between the seat and the base. ### Claim 8 (depends on 7) The carseat of claim 7, wherein the two vertical points of engagement comprise a pair of securing latches positioned toward the rear end of the base which extend vertically away from the base and a complementary pair of receiving apertures defined in the exterior surface of the seat, the receiving apertures receive the opposed securing latches to secure the seat to the base. ### Claim 9 (depends on 7) The carseat of claim 7, wherein the two side points of engagement comprise left and right slots defined in the base and a complementary pair of retractable securing projections positioned on the left and right sides of the exterior surface of the seat, the side slots receive the retractable projections to secure the seat to the base. ### Claim 10 (depends on 7) The carseat of claim 7, wherein the seat has a head end and a foot end, and the actuator control is positioned at the head end of the seat on the exterior surface of the seat. ### Claim 11 A locking system for connecting a plurality of parts of a multi-part carseat, the system comprising: a base comprising an upper surface that receives a passenger seat, front and rear ends, opposed sides and a bottom surface dimensioned to rest upon a vehicle seat, the base including four locking points comprising two spaced apart locking points positioned toward the rear end of the base and two spaced apart locking points positioned toward the front end of the base; a passenger seat that is dimensioned to be received by the upper surface of the base and includes locking elements that engage with the four locking points of the base; and an actuator that releases the locking engagement between the seat and the base. ### Claim 12 A system for locking together a plurality of parts of a multi-part travel seat, the system comprising: a base comprising an upper surface that receives a passenger seat, front and rear ends, opposed sides, two spaced apart locking points positioned toward the rear end of the base, two spaced apart locking points positioned toward the front end of the base, and a lower surface configured to rest on a vehicle seat; a passenger seat that is dimensioned to be received by the upper surface of the base and includes four locking elements that are respectively positioned and configured for releasable engagement with a respective one of the locking points of the base; and an actuator that releases the locking engagement between the locking elements of the seat and the locking points of the base.
