Abstract
Abstract A method of constructing a brake pedal comprises the steps of generating a continuous tubular member (18) by pultruding a thermoplastic or B staged thermosetting plastic resin through a die (16), attaching cross members (26 and 28) to the continuous tubular member (18), cutting the continuous tubular member (18) into segments (30 . . . 30 N ) of predetermined length, and deforming each segment (30 . . . 30 N ) to substantially define a pedal (60). The resin carries strands (14) and the segments (30 . . . 30 N ) are exposed to heat and pressure to permanently set the shape of the pedal (60). The cross members (26 and 28) are used to pivotally secure the brake pedal (60) to a vehicle in its installed position and also to connect the brake pedal (60) to an input member for a master cylinder or brake booster assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A method for constructing a brake pedal having one end adapted for pivotal anchoring and the other end substantially defining a pedal cooperating with a foot during a brake application, said method comprising: (a) generating a continuous tubular member of thermoplastic material; (b) attaching a plurality of cross members to said continuous tubular member by impacting said plurality of cross members against said continuous tubular member to extend therethrough; (c) cutting said continuous tubular member into segments containing an equal number of cross members; (d) deforming one end of each segment to substantially define the pedal; and (e) folding the other end of each segment to substantially encircle one of said cross members.
Claim 2
Independent Claim
113 words
A method for constructing a brake pedal having one end adapted for pivotal anchoring and the other end substantially defining a pedal cooperating with a foot during a brake application, said method comprising: (a) generating a continuous tubular member of thermoplastic material; (b) attaching a plurality of cross members to said continuous tubular member by impacting said plurality of cross members against said continuous tubular member to extend therethrough; (c) cutting said continuous tubular member into segments containing an equal number of cross members; (d) deforming one end of each segment to substantially define the pedal; and (e) folding the other end of each segment to substantially encircle one of said cross members.
Claim 3
Dependent Claim
17 words
The method of claim 1 in which each of said segments is provided with two cross members.
Claim 4
Dependent Claim
49 words
The method of claim 1 in which said continuous tubular member is heated prior to the attachment of said plurality of cross members to soften said continuous tubular member, and each of said segments is also heated after said other end is folded to cure each of said segments.
Claim 5
Independent Claim
132 words
A method of constructing a brake pedal having one end adapted for pivotal anchoring relative to a vehicle frame and another end defining a pedal cooperating with a foot of a vehicle operator, said method comprising, generating a continuous member of thermoplastic material by pultruding fiber strands through a resin solution, attaching a plurality of cross members to said continuous member by impacting said plurality of cross members against said continuous member to extend completely therethrough, cutting said continuous member into segments containing an equal number of cross members, said equal number of cross members being disposed remote from one end of said segment, deforming said one end of each segment to substantially define said pedal, and folding the other end of each segment to substantially encircle one of said cross members.
Claim 6
Independent Claim
132 words
A method of constructing a brake pedal having one end adapted for pivotal anchoring relative to a vehicle frame and another end defining a pedal cooperating with a foot of a vehicle operator, said method comprising, generating a continuous member of thermoplastic material by pultruding fiber strands through a resin solution, attaching a plurality of cross members to said continuous member by impacting said plurality of cross members against said continuous member to extend completely therethrough, cutting said continuous member into segments containing an equal number of cross members, said equal number of cross members being disposed remote from one end of said segment, deforming said one end of each segment to substantially define said pedal, and folding the other end of each segment to substantially encircle one of said cross members.
