  • the protrusion 218 may extend through the loop 216, thereby directly coupling the second latch pull 202 to the first actuation mechanism 182a.
  • the first actuation mechanism 182a is rotatably mounted to the first base portion 60. Accordingly, when a force is applied to the first actuation mechanism 182a, the first actuation mechanism 182a is configured to rotate about an axis. This rotation may apply a pulling force to the second latch pull 202 via the engagement between the loop 216 and the protrusion 218 of the first actuation mechanism 182a. As the second latch pull 202 translates toward the front end 66 of the first base portion 60 in response to the pulling force, the second latch pull 202 engages and applies a force to the end of the third receiving component 172c, causing the third receiving component 172c to pivot about its axis to an unlocked position.
  • the second latch pull 202 is coupled to the pivot member 210 at a location offset from the rotational axis of the pivot member 210, the pulling force acting on the second latch pull 202 is transmitted to the pivot member 210, thereby causing the pivot member 210 to rotate about its axis.
  • Rotation of the pivot member 210 causes a similar translation of the first latch pull 190 away from the axis of the pivot member 210.
  • This movement of the first latch pull 190 causes the first and second receiving components 172a, 172b to pivot about their respective axes toward an unlocked position.

  • a post or other protrusion 222 may extend from a surface 224 of the pivot member 210, and a loop 226 may be formed at the end 228 of the tension member 220 coupled thereto. In the illustrated, non-limiting embodiment, the loop 226 is greater in size than the post 222, thereby allowing a limited translational movement of the post 222 relative to the loop 226 of the tension member 220.
  • the second actuation mechanism 182b may be translatable and/or rotatable relative to the first base portion 60 in response to application of a force to the second actuation mechanism 182b.

  • the post 222 is arranged in contact with an edge of the loop 226, and the pulling force applied to the tension member 220 is transmitted to the post 222 via this engagement. Because the tension member 220 is operably coupled to the pivot member 210 at a location offset from the axis of rotation of the pivot member 210, the force transmitted to the pivot member 210 via the tension member 220 causes the pivot member 210 to rotate about its axis.

  • the recline actuator 252 is directly coupled to the recline foot lock 260; however, embodiments where the recline actuator 252 is indirectly coupled to the recline foot lock 260, such as via a tension member for example, are also contemplated herein.
  • Application of the force to the recline foot lock 260 causes the recline foot lock 260 to pivot about its axis in a first direction.
  • This rotation of the recline foot lock 260 causes the engagement feature 264 thereof to separate from a corresponding recline groove 270 formed in the recline foot 250.
  • the recline foot 250 may be moved relative to the support base 22 to adjust the angle of incline thereof.
  • a biasing member is operably coupled to the recline foot lock 260 and is configured to bias the engagement feature 264 of the recline foot lock 260 into engagement with the recline grooves 270 of the recline foot 250.
  • the biasing force of the biasing member may cause the recline foot lock 260 to pivot about its axis and the engagement feature 264 to engage an adjacent recline groove 270, thereby locking the recline foot 250 in position relative to the support base 22.
  • the support base 22 includes a level indicator 280 configured to indicate an orientation of the support base 22 relative to a horizontal plane.
  • the level indicator 280 may include a central body 282 movably mounted to the support base 22.
  • the central body 282 is pivotally mounted to the second base portion 62 of the support base 22.
  • An indicator member 284 may be arranged at a first end of the central body 282, and a mass 286 may be arranged at a second, opposite end of the central body 282.
  • the indicator member 284 is positioned vertically above the pivot axis and the mass 286 is positioned vertically beneath the pivot axis.
  • the indicator member 284 may be disposed within a slot 288 formed at an exterior surface of the support base 22. As the central body pivots about the axis, the indicator member 284 is configured to translate within the slot 288. The gravitational forces acting on the mass 286 will cause the central body 282 to rotate about its axis until the mass 286 reaches equilibrium along a vertical axis.
  • the second base portion 62 may include a respective base seat 300 and a base back 302 extending from an end of the base seat 300 at an angle.
  • a seat belt lock-off assembly 310 is positioned at the second base portion 62, such as at the base back 302 for example.
  • the seat belt lock-off assembly 310 may be disposed at an opposite surface of the base back 302 as the recline actuator 252.
  • embodiments where the seat belt lock-off assembly 310 is arranged at the base seat 300 are also within the scope of the disclosure.
  • the seat belt lock-off assembly 310 is operable to secure a vehicle belt of the vehicle seat to the support base 22.
  • the seat belt lock-off assembly 310 may include a belt lock-off member 312.
  • an opening 314 is formed at a front surface 316 of the base back 302, and the belt lock-off member 312 is receivable within the opening 314.
  • a contour of the interior surface of the opening 314 may be complementary to a contour of the belt lock-off member 312 such that the substantial entirety of the belt lock-off member 312 is receivable within the opening 314.
  • a vehicle belt (not shown) associated with a vehicle seat is positionable along a belt receiving path defined between the base back 302 of the support base 22 and the belt lock-off member 312.
  • the belt lock-off member 312 is selectively movable relative to the front 316 of the base back 302 to adjust the tension applied to the vehicle belt along the vehicle belt receiving path.
  • the belt lock-off member 312 may be configured to pivot about at least one axis between an open position and a closed position to selectively tension the portion of the vehicle belt sandwiched between the belt lock-off member 312 and the opening 314.
  • rotation of the belt lock-off member 312 to the closed position presses the vehicle belt into the opening 314, thereby tensioning the vehicle belt.
  • This tension couples the support base 22 to the vehicle belt, thereby restricting movement of the child seat (not shown) and the support base 22 relative to the vehicle seat 10.
