Front seat aranged in a two-door motor vehicle

Claim 2

An adjustable front seat for a two-door motor vehicle that has a back rest which has a forward-tilting and an inclination-adjusting movement that takes place about a single axis; wherein locking of the backrest is obtained by a catch pin being engaged by a fork latch; wherein the locking is cancelled as a result of pivoting away of a spring-loaded detent pawl from the fork latch; wherein, when a locking position is reached, the spring loaded detent pawl falls into the fork latch; wherein, when a locking position is reached, the spring loaded detent pawl interacts with a switch member to generates a signal when the detent pawl has not fallen into the fork latch; wherein when an associated vehicle door is closed and when an ignition key is inserted into an ignition switch, the signal activates a backrest-pivoting means for pivoting the backrest forward while the momentary backrest inclination movement position is maintained; wherein the backrest pivoting causes the fork latch, which is supported against the catch pin, to pivot about the catch pin until the detent pawl falls into the fork latch; and wherein the detent pawl falling into the fork latch causes the signal to stop.

Claim 3

An adjustable front seat for a two-door motor vehicle that has a back rest which has a forward-tilting and an inclination-adjusting movement that takes place about a single axis; wherein locking of the backrest is obtained by a catch pin being engaged by a fork latch; wherein the locking is cancelled as a result of pivoting away of a spring-loaded detent pawl from the fork latch; wherein, when a locking position is reached, the spring loaded detent pawl falls into the fork latch; wherein there are two backrest-locking mechanisms located opposite one another on opposite sides of the seat; wherein when the locking position is reached, the detent pawl of each backrest locking mechanism falls into an associated fork latch; wherein each detent pawl interacts with a switch member to generate a signal when a respective detent pawl has not fallen in to its respective fork latch and two signals when both detent pawls have not fallen into their respective fork latches; wherein when an associated door is closed and when an ignition key is inserted into an ignition switch, a signal will trigger at least one of a visual and acoustic alarm; wherein when two signals occur, the signals active a backrest-pivoting means for effecting pivoting of the backrest forwards while the momentary backrest movement inclination is maintained; wherein the backrest pivoting causes the fork latches, which are supported against a respective catch pin, to pivot about the catch pin until at least one of the detent pawls falls into its fork latch; and wherein the falling in of one detent pawl into its associated fork latch causes its signal to stop.

Claim 4

An adjustable front seat for a two-door motor vehicle that has a back rest which has a forward-tilting and an inclination-adjusting movement that takes place about a single axis; wherein locking of the backrest is obtained by a catch pin being engaged by a fork latch; wherein the locking is cancelled as a result of pivoting away of a spring-loaded detent pawl from the fork latch; wherein, when a locking position is reached, the spring loaded detent pawl falls into the fork latch; wherein there are two backrest-locking mechanisms located opposite one another on opposite sides of the seat; wherein when the locking position is reached, the detent pawl of each backrest locking mechanism falls into an associated fork latch; wherein each detent pawl interacts with a switch member to generate a signal when a respective detent pawl has not fallen in to its respective fork latch and two signals when both detent pawls have not fallen into their respective fork latches; wherein when an associated door is closed and when an ignition key is inserted into an ignition switch, a signal will trigger at least one of a visual and acoustic alarm; wherein when two signals occur, the signals active a backrest-pivoting means for effecting pivoting of the backrest forwards while the momentary backrest movement inclination is maintained; wherein the backrest pivoting causes the fork latches, which are supported against a respective catch pin, to pivot about the catch pin until at least one of the detent pawls falls into its fork latch; and wherein the falling in of one detent pawl into its associated fork latch causes its signal to stop.

Claim 5

A front seat according to claim 2, wherein after one signal has lapsed, the fork latches are pivoted further for an additional short predetermined period of time.
