Headrest, vehicle, and method of adjusting the headrest

A vehicle comprising:

• a body defining a passenger compartment;
• and
• a seat disposed within the passenger compartment and including:
• a seat frame;
• a seating surface supported by the seat frame;
• and
• a headrest attached to the seat frame and including:
• a housing defining a channel therethrough;
• a primary support cushion disposed on the housing;
• and
• an extension cushion disposed within the channel and translatable between a stowed position in which the extension cushion is stored within the channel and an extended position in which the extension cushion extends from the channel;
• wherein the housing has:
• a central longitudinal axis;
• a horizontal axis that is perpendicular to the central longitudinal axis;
• a first lateral side spaced apart from the central longitudinal axis along the horizontal axis;
• and a second lateral side spaced apart from the central longitudinal axis and the first lateral side along the horizontal axis;
• wherein the housing further defines:
• a first void at a first end of the channel that extends along a first axis that is substantially parallel to the central longitudinal axis on the first lateral side;
• and a second void at a second end of the channel that extends along a second axis that is substantially parallel to the central longitudinal axis on the second lateral side;
• and wherein the extension cushion is translatable along the horizontal axis to thereby be capable of extending out of either the first void or the second void in the extended position.

A method of adjusting a headrest, the method comprising:

• determining whether a vehicle is in a parked state or a driving state and whether an actuator is in an on condition or an off condition;
• wherein the vehicle includes:
• a body defining a passenger compartment;
• and
• a seat disposed within the passenger compartment and including:
• a seat frame;
• a seating surface supported by the seat frame;
• and
• a headrest attached to the seat frame and including:
• a housing defining a channel therethrough;
• a primary support cushion disposed on the housing;
• and
• an extension cushion disposed within the channel and translatable between a stowed position in which the extension cushion is stored within the channel and an extended position in which the extension cushion extends from the channel;
• wherein the housing has:
• a central longitudinal axis;
• a horizontal axis that is perpendicular to the central longitudinal axis;
• a first lateral side spaced apart from the central longitudinal axis along the horizontal axis;
• and a second lateral side spaced apart from the central longitudinal axis and the first lateral side along the horizontal axis;
• wherein the housing further defines:
• a first void at a first end of the channel that extends along a first axis that is substantially parallel to the central longitudinal axis on the first lateral side;
• and a second void at a second end of the channel that extends along a second axis that is substantially parallel to the central longitudinal axis on the second lateral side;
• and wherein the extension cushion is translatable along the horizontal axis to thereby be capable of extending out of either the first void or the second void in the extended position;
• if the actuator is in the off condition, holding the headrest within the channel such that the extension cushion does not translate from the stowed position to the extended position;
• if the actuator is in the on condition and the vehicle is in the driving state, at least one of:
• holding the headrest within the channel such that the extension cushion does not translate from the stowed position to the extended position;
• and
• automatically translating the headrest from the extended position to the stowed position;
• and
• if the actuator is in the on condition and the vehicle is in the parked state, translating the headrest from the stowed position to the extended position to thereby adjust the headrest.
