Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 177 words
A one-piece molded pedal for a motor vehicle comprising: a first hollow closed profile section, and a second U-shaped profile section molded onto an end of said first hollow closed profile section, said U-shaped profile section having a stepping plate molded thereon, side walls of the U-shaped profile section extending as respective continuations of side walls of said first section, wherein first and second reinforcing ribs join the side walls of the U-shaped profile section with one another and extend toward the open side of said U-shaped profile section such that they form wedge shaped hollow spaces together with said side walls, said wedge shaped hollow spaces expanding toward said open side, whereby said reinforcing ribs reinforce said second section adjacent the stepping plate while accommodating molding of said second section, and wherein further reinforcing ribs are provided which join a bridge part of said U-shaped profile section at a position intermediate the side walls of the U-shaped profile section, said further reinforcing ribs protruding only partially into at least one of the wedge shaped hollow spaces.
Claim 2
Dependent Claim 177 words
A one-piece molded pedal for a motor vehicle comprising: a first hollow closed profile section, and a second U-shaped profile section molded onto an end of said first hollow closed profile section, said U-shaped profile section having a stepping plate molded thereon, side walls of the U-shaped profile section extending as respective continuations of side walls of said first section, wherein first and second reinforcing ribs join the side walls of the U-shaped profile section with one another and extend toward the open side of said U-shaped profile section such that they form wedge shaped hollow spaces together with said side walls, said wedge shaped hollow spaces expanding toward said open side, whereby said reinforcing ribs reinforce said second section adjacent the stepping plate while accommodating molding of said second section, and wherein further reinforcing ribs are provided which join a bridge part of said U-shaped profile section at a position intermediate the side walls of the U-shaped profile section, said further reinforcing ribs protruding only partially into at least one of the wedge shaped hollow spaces.
Claim 3
Dependent Claim 18 words
Pedal according to claim 1, wherein the first and second profile sections are divided by an intermediate wall.
Claim 4
Dependent Claim 23 words
Pedal according to claim 2, wherein the intermediate wall extends from a rear outer wall of the pedal to the second reinforcing rib.
Claim 5
Dependent Claim 41 words
Pedal according to claim 2, wherein the first and second reinforcing ribs extend at an angle into a front outer wall of the pedal, and the hollow space situated between the reinforcing ribs has the front outer wall as its bottom.
Claim 6
Dependent Claim 59 words
Pedal according to claim 2, wherein the outside surfaces of the pedal, which otherwise have smooth surfaces, have edge-side ribs as an extension of the outside surfaces of a rear wall, which edge-sided ribs are provided in an area of the section carrying the stepping plate and/or in the area of an arm of the additional section as ribs.
Claim 7
Dependent Claim 41 words
Pedal according to claim 1, wherein the first and second reinforcing ribs extend at an angle into a front outer wall of the pedal, and the hollow space situated between the reinforcing ribs has the front outer wall as its bottom.
Claim 8
Dependent Claim 63 words
Pedal according to claim 6, wherein an intermediate wall of the pedal extends from a rear outer wall to the first reinforcing rib, wherein the second reinforcing rib and the rear outer wall and the intermediate wall enclose wedge-shaped hollow spaces, and wherein a substantially rectangular hollow space situated between the first and second reinforcing ribs has the intermediate wall as the bottom.
Claim 9
Dependent Claim 38 words
Pedal according to claim 7, wherein the further reinforcing ribs are arranged in a longitudinal plane between a rear outer wall and the second reinforcing rib as well as between the stepping plate and the first reinforcing rib.
Claim 10
Dependent Claim 59 words
Pedal according to claim 6, wherein the outside surfaces of the pedal, which otherwise have smooth surfaces, have edge-side ribs as an extension of the outside surfaces of a rear wall, which edge-sided ribs are provided in an area of the section carrying the stepping plate and/or in the area of an arm of the additional section as ribs.
Claim 11
Dependent Claim 63 words
Pedal according to claim 1, wherein an intermediate wall of the pedal extends from a rear outer wall to the first reinforcing rib, wherein the second reinforcing rib and the rear outer wall and the intermediate wall enclose wedge-shaped hollow spaces, and wherein a substantially rectangular hollow space situated between the first and second reinforcing ribs has the intermediate wall as the bottom.
Claim 12
Dependent Claim 38 words
Pedal according to claim 1, wherein the further reinforcing ribs are arranged in a longitudinal plane between a rear outer wall and the second reinforcing rib as well as between the stepping plate and the first reinforcing rib.
Claim 13
Dependent Claim 52 words
Pedal according to claim 11, wherein the further reinforcing ribs are connected by way of a partial area with the first and second reinforcing ribs in the longitudinal plane and these further reinforcing ribs extend by way of rib surfaces into the second section of the pedal and come to an end.
Claim 14
Dependent Claim 41 words
Pedal according to claim 11, wherein the further reinforcing ribs are arranged in a longitudinal plane on an interior side of a front outer wall and have a shape corresponding to a curved contour of the pedal between the two sections.
