Claim 12

The combination of claim 10, the pivotal connection of said lower headrest connector link to said headrest crank being closer to the pivotal connection of said headrest crank to said back mounting link than to the pivotal connection of said headrest crank to said upper headrest connector link.

Claim 13

The combination of claim 11, and the pivotal connection of said upper headrest connector link to said headrest driver link, being closer to the pivotal connection of said headrest driver link to said back mounting link than the pivotal connection of said headrest driver link to said headrest bracket.

Claim 14

The combination of claim 12, the pivotal connections of said upper headrest connector link to said headrest driver link and to said headrest crank, and the pivotal connection of said headrest crank to said back mounting link, being substantially in a straight line, in the T.V. position of said back mounting link.

Claim 15

The combination of claim 1, said front pivot link having an arm extending downwardly below its pivotal connection to said toggle bar, a carrier link pivoted at one end to the lower end of said arm of said front pivot link, a seat control link pivotally connected to said carrier link and to said seat link, and a main link pivotally connected to said arm mounting link and to said carrier link, a bellcrank pivoted mediately the ends thereof, to said arm mounting link, said bellcrank having a pair of arms, the rear end of said carrier link being pivoted to one arm of said bellcrank, a headrest actuator link pivoted to another arm of said bellcrank, a headrest control link pivoted, at one end, to said back mounting link and pivoted to the other end of said headrest actuator link, a headrest bracket forming part of a four bar linkage with a portion of said back mounting link, and means controlled by said headrest control link, to project and retract said headrest bracket four bar linkage, said link which is pivoted to said front pivot link and to said seat link, comprising a legrest actuator link, a legrest bracket, and legrest linkage connecting said legrest bracket with said legrest actuator link and seat link to project said legrest bracket upon swinging the upper end of said back mounting link from upright position to T.V. position.

Claim 16

The combination of claim 1, a legrest bracket, and legrest linkage connecting the legrest bracket with said seat link and with said means, to project said legrest bracket upon moving said back mounting link from upright position to reclined position, a headrest bracket, and headrest linkage connecting said headrest bracket with said back mounting link and with said means, to project said headrest bracket as said back mounting link swings back from upright position to reclined position, and to retract said headrest bracket as said back mounting link swings back from reclined position to upright position, and to retract said headrest bracket as said back mounting link swings back from reclined position to upright position, said toggle bar and said arm of said back mounting link having means adapted to contact one another in the fully reclined position of said back mounting link to prevent retraction of the legrest linkage when the back mounting link is in fully reclined position.
