## Abstract

A seat assembly can include a base, a linkage assembly, a seat, and an energy-management assembly. The linkage assembly can be supported by the base and include a return plate supported by the base for rotation about a first axis of rotation. The seat can be supported by the linkage assembly for movement relative to the base along a generally arcuate path. The return plate can be operable to rotate relative to the seat about a second axis of rotation. The energy-management assembly can be supported by the base for rotation about a third axis of rotation and supported by the return plate for rotation about a fourth axis of rotation. The energy-management assembly can include a biasing member configured to resist the movement of the seat relative to the base along the generally arcuate path.

## Claims

### Claim 1

A seat assembly comprising:
a base;
a linkage assembly supported by the base, the linkage assembly including a return plate supported by the base for rotation about a first axis of rotation;
a seat supported by the linkage assembly for movement relative to the base along a generally arcuate path, the return plate operable to rotate relative to the seat about a second axis of rotation; and
an energy-management assembly supported by the base for rotation about a third axis of rotation and supported by the return plate for rotation about a fourth axis of rotation, the energy-management assembly including a biasing member configured to resist the movement of the seat relative to the base along the generally arcuate path.

### Claim 2 (depends on 1)

The seat assembly of claim 1, wherein the energy-management assembly is configured to resist rotation of the linkage assembly when the seat assembly is in a first configuration.

### Claim 3 (depends on 2)

The seat assembly of claim 2, wherein the energy-management assembly is configured to produce a biasing torque about the first and second axes of rotation.

### Claim 4 (depends on 1)

The seat assembly of claim 1, wherein the energy-management assembly includes a damper.

### Claim 5 (depends on 1)

The seat assembly of claim 1, wherein the seat is operable to follow a generally arcuate path between a first configuration and a second configuration.

### Claim 6 (depends on 1)

The seat assembly of claim 1, wherein the linkage assembly further comprises a first rocking member supported by the base for rotation about the first axis of rotation, the first rocking member further supported by the return plate for rotation about the second axis of rotation.

### Claim 7 (depends on 6)

The seat assembly of claim 6, wherein the linkage assembly further comprises a second rocking member supported by the base for rotation about a fifth axis of rotation.

### Claim 8 (depends on 7)

The seat assembly of claim 7, wherein the seat is operable to rotate relative to the second rocking member about a sixth axis of rotation.

### Claim 9 (depends on 1)

The seat assembly of claim 1, further comprising:
a seat back having a seat belt aperture; and
a seat belt system including a strap member extending through the seat belt aperture.
