In the illustrated embodiment, the first pivot aperture  258  is configured to receive the torsion bar  100 , as discussed elsewhere herein. The sector arm  16  may be secured on the torsion bar  100  by a washer  308  and may be disposed so that a first surface  312  of the sector arm  16  is substantially flush against an interior surface  316  of the second horizontal support  98  ( FIGS. 8 and 9 ). The second end  304  of the sector arm  16  defines the second pivot aperture  218  which is configured to receive the pivot pin  200 . In the illustrated embodiment, the pivot pin  200  operably couples the sector arm  16  to the striker plate  192 . The second end  304  of the sector arm  16  further defines the second pivot axis β extending through the center of the second pivot aperture  218  and aligned with the pivot pin  200 . As shown in  FIGS. 6, 8, and 9 , the first pivot axis α allows the sector arm  16  to rotate about the torsion bar  100  of the base frame  74  when the seating assembly  10  is lifted by the sector arm  16 . The second pivot axis β allows the sector arm  16  to rotate between the raised position and the lowered position as the latch assembly  168  is actuated. 
     Still referring to  FIGS. 8 and 9 , the elongated member  298  of the sector arm  16  forms an obtuse angle Y ( FIGS. 9 and 10A ). The dual cam latch  24  is disposed proximate to the middle of the sector arm  16  where angle Y is formed. The second pivot aperture  218  is defined by the second end  304  of the member  298  so that the second pivot axis β is a first distance from an opening  334  defined by the locking hook  338  of the dual cam latch  24 . The first distance is equivalent to a second distance, and the second distance is measured from the second pivot axis β to the striker pin  12 . When the sector arm  16  is in the down position, the striker pin  12  is received by the opening  334 , defined by the locking hook  338  of the latch assembly  168 . The obtuse angle Y of the sector arm  16  allows both the base frame  74  and a section of the sector arm  16  to be substantially parallel with the track assembly  14  when the sector arm  16  is in the lowered position. The elongated member  298  of the sector arm  16  may include an offset  342  proximate to the second end  304 .

Similarly, the structural cam  450  and the adjustment cam  452  are operable between a blocked position and a removed position. The blocked position of the structural cam  450  and the adjustment cam  452  corresponds to the locked position of the locking hook  338 . Similarly, the removed position of the structural cam  450  and the adjustment cam  452  corresponds to the unlocked position of the locking hook  338 . 
     Referring now to  FIG. 11A , the locking hook  338  is shown in the locked position. In the illustrated embodiment, the side edge  596  of the first flange  580  of the locking hook  338  is substantially flush with the top edge  508  of the adjustment cam  452 . The tab  494  of the adjustment cam  452  is not fully engaged with the notch  524  of the structural cam  450 , and the return spring  624  is in a neutral position. When the locking hook  338  is in the locked position, the second flange  588  is positioned to prevent the striker pin  12  from being removed from the opening  334 . To secure the striker pin  12 , the end  606  of the locking hook  338  is aligned with the downward extending flange  416  of the sector arm  16 . The top edge  508  of the adjustment cam  452  abutting the side edge  596  of the first flange  580  of the locking hook  338  prevents the locking hook  338  from rotating out of the locked position. The locking hook  338  will remain in the locked position until acted upon by a force that also rotates the adjustment cam  452  and the structural cam  450  out of the blocked position. 
     Referring now to  FIG. 11B , when the latch assembly  168  is actuated by the first or second latch cable  130 ,  132 , a force F 1  is applied to the structural cam  450  by the first or second latch cable  130 ,  132 . The force F 1  applies tension on the return spring  624 , resulting in a force F 2  being exerted on the locking hook  338  through the return spring  624 . The side edge  596  of the first flange  580  of the locking hook  338  remains in contact with the adjustment cam  452 . When the force F 1  is applied to the structural cam  450 , the structural cam  450  rotates about the third connection pin  394  until the tab  494  fully engages with the notch  524  of the adjustment cam  452 . When the tab  494  fully engages with the notch  524 , a moment M 1  is applied to the adjustment cam  452  and cinching spring  440  (not shown). The moment M 1  is applied generally clockwise about the third connection pin  394  as the tab  494  remains fully engaged with the notch  524  and the foot  516  of the adjustment cam  452  begins to move in a clockwise direction. 
     Referring now to  FIGS. 11C and 11D , the first or second latch cable  130 ,  132  continues to apply the force F 1  to the structural cam  450 . The structural cam  450  continues to move in a generally rearward direction, applying the moment M 1  to the adjustment cam  452 . As the adjustment cam  452  rotates, the top edge  508  of the adjustment cam  452  is gradually moved out of contact with the side edge  596  of the locking hook  338 . When the top edge  508  of the adjustment cam  452  is removed from contact with the side edge  596 , the locking hook  338  is free to rotate about the second connection pin  392 . The structural cam  450  continues applying tension to the return spring  624 , continuing to apply the force F 2  on the locking hook  338 . As the force F 2  on the locking hook  338  increases, a moment M 2  is applied generally clockwise about the second connection pin  392 , rotating the locking hook  338  into the unlocked position, as shown in  FIG. 11D . The locking hook  338  will remain in the unlocked position until it receives the striker pin  12 . When the striker pin  12  is received by the opening  334  defined by the locking hook  338 , the striker pin  12  pushes the first flange  580  upwards when it contacts the side edge  596  of the first flange  580 . When the locking hook  338  reaches the locked position, the cinching spring  440  rotates the adjustment cam  452  back into the blocked position, allowing the side edge  596  to contact the top edge  508  of the adjustment cam  452  and securing the locking back into the locked position. 
     Referring now to  FIGS. 11A-11D , the structural cam  450  and the adjustment cam  452  are disposed to allow the locking hook  338  to contact only the adjustment cam  452 .

The first pivot pin  850  is configured to allow the first arm  800  to rotate into the pitched position without adjusting the second arm  804 . When the latch assembly  168  is released, the first arm  800  of the sector arm  16  rotates into the pitched position P, leaving the second arm  804  stationary. The second arm  804  may be moved independently from the first arm  800 , as described elsewhere herein. 
     Referring now to  FIGS. 17A and 17B , the release cam  28  is operably coupled to the first arm  800  of the sector arm  16  by the second pivot pin  828 . The release cam  28  includes a body portion  884  defining a connection aperture  888 . A foot  892  extends perpendicularly to the body portion  884 . The release cam  28  is fixedly coupled to the first arm  800  of the sector arm  16  so that the release cam  28  pivots with the first arm  800  when the sector arm  16  is rotated about the second pivot pin  828 . The release bar  30  is positioned beneath the base frame  74  and extends proximate to the release cam  28 . The release bar  30  includes the rear portion  34  and the front portion  32 . As shown in  FIGS. 12A and 14A , the front portion  32  of the release bar  30  includes a forward bar  900  protruding from the base frame  74  toward the front of the seating assembly  10 . The forward bar  900  is integrally formed with side bars  904  that are configured to extend beneath the base frame  74 . Referring again to  FIGS. 17A and 17B , each of the side bars  904  includes a spring end  906  positioned at a predetermined angle to the side bar  904 . The spring end  906  is disposed to engage with the torsion spring  728 . When the forward bar  900  of the front portion  32  is engaged, the spring end  906  subsequently engages the torsion spring  728 . When the torsion spring  728  is engaged, the rear portion  34  engages a release spring  916 . 
     Still referring to  FIGS. 17A and 17B , the rear portion  34  includes a first curve  908  integrally formed with a second curve  912 . The second curve  912  is an inverted curve of the first curve  908 . The second curve  912  is integrally formed with a second spring end  910  and is selectively engageable with the release spring  916 . The release spring  916  is operably coupled to the track assembly  14 . When the second curve  912  is depressed, the release spring  916  is released to allow fore/aft movement of the base frame  74  relative to the track assembly  14 . The second curve  912  may be depressed by the release cam  28  or by the user raising the front portion  32  of the release bar  30 . 
     Referring still to  FIGS. 17A and 17B , the release cam  28  is rotated into an engaged position when the latch assembly  168  is moved into the pitched position ( FIG. 17B ). When the release cam  28  is rotated into the engaged position, the release cam  28  extends generally downward to depress the rear portion  34  of the release bar  30 . The release cam  28  engages the first curve  908  of the rear portion  34  of the release bar  30 . When the first curve  908  is depressed, the second curve  912  engages the release spring  916  to allow fore/aft movement of the base frame  74  relative to the track assembly  14 . It is contemplated that other configuration of the release spring  916  may be used. It is also contemplated that other shape configurations for the release bar  30  may be used without departing from the scope of the present disclosure. 
     Referring now to  FIGS. 18A and 18B , the sector arm  16  is operable between the design position D ( FIG. 18A ) and the pitched position P ( FIG. 18B ). As discussed elsewhere herein, the second arm  804  of the sector arm  16  includes the gear edge  838 . The gear edge  838  includes a plurality of gear teeth  930 . A pinion  934  is disposed proximate to the gear edge  838 . The pinion  934  is generally cylindrical and may include a plurality of gear slots  938  defined by a lateral edge  942  of the pinion  934 . The plurality of gear teeth  930  is configured to be received by the plurality of gear slots  938 . The plurality of gear teeth  930  and the plurality of gear slots  938  allow the second arm  804  to be selectively operable between the design position, the raised position, and a multitude of positions between the design position and the raised position. As shown in  FIGS. 12B, 13, 14B, 15, 18A, and 18B , the pinion  934  is actuated using an actuator  960  and a cable  964  operably coupled to the base frame  74 . When the actuator  960  is engaged, it ratchets the gear edge  838  upward to allow the second arm  804  to raise the base frame  74 . As the second arm  804  raises, the hinge arm  188  gradually rotates as well to allow the base frame  74  to remain substantially parallel to the track assembly  14  as it raises. The second arm  804  is operable when the first arm  800  is in any position. By utilizing the raised position, it is possible to increase the cone of entry C shown in  FIG. 14B  to allow access to space rearward of the seating assembly  10 .
