ABSTRACT:
An infant seat having a seating surface positionable between upright and reclined orientations, the seating surface being supported by arms which are connected to torsion springs in a base, the torsion springs providing a bouncing motion to the seating surface in both the upright and reclined orientations. The base includes a rear support member which pivots between a support position, in which the member is substantially coplanar with the base, and a collapsed or folded position, in which the support member is pivoted adjacent to the seating surface. In a preferred embodiment, the connection between the seating surface and support arms includes a pivot plate pivotally connected to the seating surface and support arms and includes a slot engaged by a shoulder rivet attached to the support arms which defines limits of pivotal movement of the seating surface. The rear support member preferably includes nock fittings at its ends which engage the torsion springs and are held in engagement by extension springs captured within the rear support member ends. When the infant seat is adjusted to the collapsed or folded position, the nock fittings are disengaged from the torsion springs and pivoted toward the seating surface.
