Vehicle pedal device capable of adjusting pedal position in longitudinal direction of vehicle

A pedal device for a vehicle, comprising:

• a depressable portion which is to be operationally depressed by a driver of the vehicle;
• an output member pivotably supported by a supporting shaft provided in a bracket that is fixed to a body of the vehicle, such that said output member is pivoted about said supporting shaft when said depressable portion is operationally depressed, for thereby applying to a motive-power transmitting member an output corresponding to a depression force which is applied to said depressable portion;
• a longitudinal adjustment device to move said depressable portion in a longitudinal direction of the body of the vehicle when said depressable portion is not being operationally depressed;
• and
• a pedal-ratio varying mechanism which is disposed between said output member and said motive-power transmitting member, and which chances a pedal ratio in relation to a depressing stroke of said pedal device,
• wherein said longitudinal adjustment device comprises
• an adjusting link supported by said supporting shaft such that said adjusting link is pivotable about said supporting shaft and is adjustably positioned in a predetermined pivoted position;
• a pedal member connected to said adjusting link such that said pedal member is pivotable relative to said adjusting link about a fourth connecting shaft parallel to said supporting shaft, said pedal member having said depressable portion so that said pedal member is pivoted about said fourth connecting shaft when said depressable portion is operationally depressed;
• and
• an interlock link connected to said pedal member such that said interlock link is pivotable relative to said pedal member about a fifth connecting shaft parallel to said supporting shaft, said interlock link being connected to said output member such that said interlock link is pivotable relative to said output member about a sixth connecting shaft parallel to said supporting shaft, said interlock link cooperating with said adjusting link to position said pedal member in a fixed posture, said interlock link being pivoted about said sixth connecting shaft when said adjusting link is pivoted, for thereby causing a circular motion of said pedal member in a longitudinal direction of the vehicle, said interlock link causing said output member to be pivoted about said supporting shaft when said pedal member is pivoted about said fourth connecting shaft with said depressable portion being operationally depressed and with said adjusting link being positioned in a predetermined pivoted position, and
• wherein a line connecting said supporting shaft and said fourth connecting shaft, a line connecting said fourth connecting shaft and said fifth connecting shaft, a line connecting said fifth connecting shaft and said sixth connecting shaft and a line connecting said sixth shaft and said supporting shaft cooperate with each other to substantially define a parallelogram, so that said pedal member is substantially parallely displaced when said adjusting link is pivoted about said supporting shaft.

• wherein said longitudinal adjustment device comprises
• an adjusting link supported by said supporting shaft such that said adjusting link is pivotable about said supporting shaft and is adjustably positioned in a predetermined pivoted position;
• a pedal member connected to a lower end portion of said adjusting link such that said pedal member is pivotable relative to said adjusting link about a fourth connecting shaft parallel to said supporting shaft, said pedal member having said depressable portion, so that said pedal member is pivoted about said fourth connecting shaft when said depressable portion is operationally depressed;
• and
• an interlock link connected at a lower end portion thereof to said pedal member such that said interlock link is pivotable relative to said pedal member about a fifth connecting shaft parallel to said supporting shaft and located rearwardly of said fourth connecting shaft, said interlock link being connected at an upper end portion thereof to said output member such that said interlock link is pivotable relative to said output member about a sixth connecting shaft parallel to said supporting shaft and located rearwardly of said supporting shaft, said interlock link cooperating with said adjusting link to position said pedal member in a fixed posture, said interlock link being pivoted about said sixth connecting shaft when said adjusting link is pivoted, for thereby causing a circular motion of said pedal member in a longitudinal direction of the vehicle, said interlock link causing said output member to be pivoted about said supporting shaft when said pedal member is pivoted about said fourth connecting shaft with said depressable portion being operationally depressed and with said adjusting link being positioned in a predetermined pivoted position, and
