Straddle-type seat

A straddle seat comprising:

• a compressible foam for seating an occupant thereon;
• a rigid base disposed below the compressible foam for attaching the compressible foam to a vehicle, the base comprising at least one opening passing therethrough and at least one lever flexibly attached to the base at a first end thereof, the at least one opening being at least partially formed within the lever such that when a second end of the lever is lifted, the lever flexes between the first and second ends and at least a portion of the opening moves with the lever;
• and
• a cover covering the compressible foam and attached to the base to hold the compressible foam and base as a single unit.

A straddle seat for use in combination with a structure of a vehicle, the structure having a forward end, a rearward end, and a top surface, the top surface including:

• a first protrusion having a first width and a first length, the first protrusion placed along a longitudinal centerline of the vehicle structure near the forward end of the vehicle structure;
• a second protrusion having a second width and a second length, the second protrusion placed along the longitudinal centerline of the vehicle structure near the rearward end of the vehicle structure;
• third and fourth protrusions having third and fourth widths and third and fourth lengths respectively, the third and fourth protrusions placed to a first side of the longitudinal centerline of the vehicle structure;
• and
• fifth and sixth protrusions having fifth and sixth widths and fifth and sixth lengths respectively, the fifth and sixth protrusions placed to an opposite side of the longitudinal centerline of the vehicle structure from the third and fourth protrusions, each protrusion extending away from the top surface and including a slot opening toward the rearward end of the vehicle structure;
• the seat comprising:
• compressible foam for seating an occupant thereon;
• a base disposed below and supporting the compressible foam for attaching the straddle seat to the vehicle structure, the base including a substantially flat middle portion with downwardly extending side portions to fit congruously with the vehicle structure, the substantially flat middle structure having,
• a first opening to receive the first protrusion, the first opening having a first width and a first length and placed along a longitudinal centerline of the base, the first length of the first opening being smaller than the first length of the first protrusion;
• a second opening to receive the second protrusion, the second opening having a second width and a second length and placed along the longitudinal centerline of the base, the second length of the second opening being larger than the second length of the second protrusion;
• third and fourth openings to receive the third and fourth protrusions respectively, the third and fourth openings have third and fourth widths and third and fourth lengths respectively and placed to one side of the longitudinal centerline of the base, the third and fourth lengths of the third and fourth openings being larger than the third and fourth lengths of the third and fourth protrusions;
• Fifth and sixth openings to receive the fifth and sixth protrusions, the fifth and six openings having fifth and sixth widths and fifth and sixth lengths respectively and placed to an opposite side of the longitudinal centerline of the base from the third and fourth openings, the fifth and sixth lengths of the fifth and sixth openings being larger than the fifth and sixth lengths of the fifth and sixth protrusions;
• and
• a cover covering the compressible foam and attached to the base to hold the compressible foam and base as a single unit.
