1. A restraint seat having an adjustable seat inclination with enhanced safety features during impact forces comprising:
- a body forming a seat;
a base, said seat adjustable to move relative to said base to a plurality of predetermined angles of inclination to allow said seat to be fixed with respect to said base at one of said angles of inclination;
said body rotatable with respect to said base from said predetermined angles of inclination anda mechanism for connecting said base to said body to allow said adjustable movement, said connecting mechanism including a spring connected to said body and said base, and a recline lever pivotally connected to said body and having a portion selectively engaging stops on said base to allow for the selective inclination of said body with respect to said base to said plurality of predetermined angles of inclination said portion of said recline lever comprising a bar slidably contained in a slot in said lever and lying traverse to said slot, said bar connected to said spring and engaging said stops at the ends of said bar, said mechanism holding said body at said predetermined angles of inclination with respect to said base during ordinary travel and adjustable to allow said seat to be fixed with respect to said base at one of said plurality of predetermined angles of inclination, but said mechanism allowing said body to move relative to said base during a sudden impact, whenever the impact forces exceed a predetermined value.

Abstract
A NHTSA-safety compliant infant restraint with a number of advantageous features including a linkage mechanism that allows relative movement between the seat and underframe during an impact, to allow for an infant to be transported reclined while the restraint is in a rear-facing mode, while enabling the restraint to comply with NHTSA standards during a crash. The restraint may be used in a forward facing, non-rotatable position as well. A plurality of seat back incline positions may be selected for both the rearward and forward-facing modes.

2. A child restraint seat convertible between an inclined travel mode for infants and an upright travel mode for toddlers, comprising:
-
an upper body forming a seat; a lower frame forming a base; means for connecting the upper body to the lower frame, said means for connecting allowing said upper body to be secured to said lower frame in a non-rigid manner to allow said seat to be substantially inclined during travel but to rotate upright with respect to said lower frame during an impact, when said means for connecting are in one position and when said seat is in a rearwardly facing position, and allowing said seat to remain substantially upright with respect to said lower frame both during travel and during an impact, when said means for connecting are in another position and when said seat is in a forwardly facing position, said means for connecting said upper body to said lower frame in a non-rigid manner comprising a mechanism having a bar supported in a slot in said mechanism, said bar extending along the mechanism transverse to the slot with the bar engaging the base and attached to spring fixed to the mechanism, said mechanism pivotally secured to said upper body, said bar free to move along said slot as the upper body moves relative to the frame upon impact. - View Dependent Claims (5, 6)

7. A restraint of unitary construction comprising:
-
a one-piece molded plastic seat; a one-piece molded plastic base, said seat capable of relative movement to said base; a non-rigid connection between said seat and said base, said non-rigid connection comprising a cradle having a spring connecting said seat to said base; whereby said seat is moveable relative to said base during an impact, and said spring is elongated in response to impact forces on said infant restraint, and said seat moves with respect to said base, in response to inertial forces, from a prone travel position to an upright crash position during impact; wherein said non-rigid connection cradle has a bar connected to said spring, said bar supported in two slots on said cradle and engaging said base at one of a plurality of recesses on said base, said cradle fixed to move with said seat, and said bar fixed to move with said base, said cradle adjustable so that said bar may engage any of said plurality of recesses to give a plurality of angles of inclination between the seat and the base.

11. A restraint seat having an adjustable seat inclination with enhanced safety features during impact forces comprising:
-
a body forming a seat; a base, said seat adjustable to move relative to said base to a plurality of predetermined angles of inclination to allow said seat to be fixed with respect to said base at one of said angles of inclination; said body rotatable with respect to said base from said predetermined angle of inclination; and a mechanism for connecting said base to said body to allow said adjustable movement, said connecting mechanism including a spring connected to said body and said base, a first rod and a second rod, said rods extending through said body and having ends projecting out the sides of said body, said connecting mechanism further including a cradle pivotally secured to said body about said first rod, said cradle containing two slots, a substantially vertically extending slot and an arcuate substantially horizontally extending slot, said vertically extending slot receiving said second rod, and having a compression spring fitted therein to engage said second rod, and said horizontally extending slot receiving a bar, said bar being positioned transverse to said horizontal slot and engaging said base at the ends thereof, said spring being attached to said bar and to said cradle, wherein said spring is elongated and said bar moves along said horizontally extending slot as said body is rotated with respect to said base, said mechanism holding said body at said predetermined angles of inclination with respect to said base during ordinary travel and adjustable to allow said seat to be fixed with respect to said base at one of said plurality of predetermined angles of inclination, but said mechanism allowing said body to move relative to said base during a sudden impact, whenever the impact forces exceed a predetermined value.
